Practice Set – 6.1

(1) Alka spends 90% of the money that she receives every month, and saves Rs. 120. How much money does she get monthly?

Ans:

Let, Alka’s monthly income is x.

According to Question, 90/100x + 120 = x

=> 9x + 1200 = 10x

=> x = 1200

∴ Monthly income = ₹1200.

(2) Sumit borrowed a capital of Rs. 50,000 to start his food products business. In the first year he suffered a loss of 20%. He invested the remaining capital in a new sweets business and made a profit of 5%. How much was his profit or loss computed on his original capital?

Ans:

Loss suffered = 20% × 50000

= 20/100 × 50000

= ₹10000

Remaining money = ₹ (50000 – 10000) = ₹40000

Profit made = 5% × 40000

= ₹2000

Capital after profit = ₹40000 + 2000

= ₹42000

Total loss suffered = ₹50000- 42000

= ₹8000

Percentage of loss = 8000/50000 × 100%

= 16%

(3) Nikhil spent 5% of his monthly income on his children’s education, invested 14% in shares, deposited 3% in a bank and used 40% for his daily expenses. He was left with a balance of Rs. 19,000. What was his income that month?

Ans:

Let, Nikhil’s income that month be ₹x

A/Q,

5% x + 14% x + 3% x + 40% x + 19000 = x

= (1 – 5/100) – 14/100) – 3/100 – 40/100) x = 19000

= (100 – 5 – 14 – 3 – 40) x = 19000 × 100

= 38x = 1900000

= x = 50000

∴ Nikhil’s income month was ₹50000

(4) Mr. Sayyad kept Rs. 40,000 in a bank at 8% compound interest for 2 years. Mr. Fernandes invested Rs. 1,20,000 in a mutual fund for 2 years. After 2 years, Mr. Fernandes got Rs. 1,92,000. Whose investment turned out to be more profitable?

Ans:

Compound interest = Amount – Principal

= P (1 + r/100)ⁿ – P

= 40000 [(1 + 8/100)² – 1]

= 40000 [(1.08)² – 1]

= ₹6656.

Percentage of interest = 6656/40000 × 100

= 16.64%

Profit on mutual funds = ₹1,92,000 – ₹1,20,000

= ₹72,000

Percentage of profit = 72000/120000 × 100

∴ Investment on mutual funds was more profitable.

(5) Sameera spent 90% of her income and donated 3% for socially useful causes. If she left with Rs. 1750 at the end of the month, what was her actual income?

Ans:

Let, ₹ x be Sameera’s actual income

According to Question, 90% x + 3% x + 1750 = x

=> (1 – 90/100 – 3/100) = 1750

=> 7x = 175000

=> x = 25,000

∴ Sameera’s actual incomes was ₹25,000

Activity:

Ex:

Mr. Pandit is 75 years of age. Last year his annual income was 13,25,000 rupees. How much is his taxable income? How much tax does he have to pay?

Ans:

13,25,000 – 10,00,000 = 3,25,000

According to the table he must first pay Rs 1,10,000 as income tax. In addition, on 3,25,000 rupees he has to pay 30% income tax.

3,25,000 × 30/100 = 97500 rupees

Therefore, his total income tax amounts to = 1,10,000 + 97,500

= 207500 rupees

Besides this, education was will be 2% of income tax

= 207500 × 2/100= 4150 rupees

Secondary & higher education tax at 1% income tax

= 207500 × 1/100 = 2075 rupees

Total income tax = income tax + education tax + secondary and higher education tax

= 207500 + 4150 + 2075

= 213725 rupees

Practice Set 6.2

(1) Observe the table given below. Check and decide, whether the individuals have to pay income tax.

(i) Mis Nikita

Ans: Need not pay income tax

(ii) Mr. Kurlkarni

Ans: Needs to pay income tax

(iii) Miss Mehta

(2) Mr. Kartarsingh (age 48 years) works in a private company. His monthly income after deduction of allowances is Rs. 42,000 and every month he contributes Rs. 3000 to GPF. He has also bought Rs. 15,000 worth of NSC (National Savings Certificate) and donated Rs. 12,000 to the PM’s Relief Fund. Compute his income tax.

Ans:

Given monthly = ₹42,000

∴ Yearly income = ₹42000 × 12 = ₹5,04,000 monthly GPF = ₹3000

Yearly GPF = ₹3000 × 12 = 36,000

NSC = ₹15000

PM’s relief fund = ₹12,000

∴ Total taxable income = ₹[5,04,000 – (36,000 + 15,000 + 12,000)]

= ₹ [5,04,000 – 63,000]

= ₹ 4,41,000

∴ Taxable amount is between 2,50,001 to 5,00,000

∴ Income tax = [441000 – 250000] × 5/100 = ₹9550

Education = 2% of 9550 = ₹191

Secondary & higher education = 1% of 9550 = ₹95.5

∴ Total tax = ₹(9550 + 191 + 95.5)

= ₹ 9836.5

Problem Set 6

(1) Write the correct alternative answer for each of the following questions.

(A) 1,50,000 rupees

(B) 2,50,000 rupees

(C) 1,00,000 rupees

(D) 2,00,000 rupees

Ans: (A) 1,50,000 rupees

(ii) A person has earned his income during the financial year 2017-18. Then his assessment year is ….

(A) 2016-17

(B) 2018-19

(C) 2017-18

(D) 2015-16

Ans: (B) 2018-19.

(2) Mr. Shekhar spends 60% of his income. From the balance he donates Rs. 300 to an orphanage. He is then left with Rs. 3,200. What is his income?

Ans:

Let, x be Mr. Shekhar’s income

A/Q,

60% x + 300 + 3200 = x

= (1 = 60/100) x = 3500

= 4x = 35000

= x = 8750

∴ Mr. Shekhar’s income is ₹8750.

(3) Mr. Hiralal invested Rs. 2,15,000 in a Mutual Fund. He got Rs. 3,05,000 after 2 years. Mr. Ramniklal invested Rs. 1,40,000 at 8% compound interest for 2 years in a bank. Find out the percent gain of each of them. Whose investment was more profitable?

Ans:

Profit on mutual funds = 3,05,000 – 2,15,000

= ₹90,000

Percentage of profit = 90,000/215000 × 100 = 41.86%

Compound Interest = 1,40,000 (1 + 8/100)² – 1,40,000

= 1,40,000 [(1.08)² – 1]

= ₹23,296

Percentage of interest = 23296/140000 × 100

= 16.64%

∴ Investment in mutual funds is more profitable.

(4) At the start of a year there were Rs. 24,000 in a savings account. After adding Rs. 56,000 to this the entire amount was invested in the bank at 7.5% compound interest. What will be the total amount after 3 years?

Ans:

Given, Total investment = Rs (24,000 + 56,000)

= Rs 80,000

∴ Amount = 80,000 (1 + 7.5/100)³

= 80,000 [1.075]³

= 99383.75

∴ Total amount after 3 years is Rs 99383.75.

(5) Mr. Manohar gave 20% part of his income to his elder son and 30% part to his younger son. He gave 10% of the balance as donation to a school. He still had Rs. 1,80,000 for himself. What was Mr. Manohar’s income?

Ans

Let, x be Mr. Manohar’s income

Balance = x – 20/100 x – 30/100 x = 5/10 x

Donation = 10% of balance = 10/100 (5/10 x) = 5/100 x

According to Question,

5/10 x + 5/100 x + 180000 = x

= (1 – 5/10 – 5/100) x = 180000

=> 45x = 18000000

=> x = 4,00,000

∴ Mr. Manohar’s income is ₹4,00,000

(6) Kailash used to spend 85% of his income. When his income increased by 36% his expenses also increased by 40% of his earlier expenses. How much percentage of his earning he saves now?

Ans:

Let, Kailash salary be 100

∴ Previous expenses = 85% of 100 = 85/100 × 100 = ₹85

New salary = 100 + 36% of 100 = ₹136

= (100 + 40) % of 85

= 140/100 × 85

= ₹119

∴ Total savings = ₹136 – ₹119

= ₹17

∴ Percentage of saving = 17/136 × 100 = 12.5%

(7) Total income of Ramesh, Suresh and Preeti is 8,07,000 rupees. The percentages of their expenses are 75%, 80% and 90% respectively. If the ratio of their savings is 16:17:12, then find the annual saving of each of them.

Ans:

Let, savings of Ramesh, Suresh and Preeti be 16x, 17x and 12x

Expenses of Ramesh = 75% of income

Savings of Ramesh = 25% of income

= 16x = 25/100 (income)

=> income = 64x

Expenses of Suresh = 80% of income

Savings of income = 20% of income

=> 17x = 20/100 (income)

=> income = 85x

Expenses of Preeti = 90% of income

Saving of Preeti = 10% of income

=> 12x = 10/100 (income)

=> 120x = income

∴ Total income = 807000

= 64x + 85x + 120x = 807000

= 296x = 807000

= x = 3000

Savings of Ramesh = 16 × 3000

= ₹48000

Savings of Suresh = 17 × 3000

= ₹51000

Savings of Preeti = 12 × 3000

= ₹36000

(8) Compute the income tax payable by following individuals.

(i) Mr. Kadam who is 35 years old and has a taxable income of Rs. 13,35,000.

Ans:

Taxable income = ₹13,35,000

∴ Income tax = ₹1,12,500 + 30% (₹13,35,000 – ₹10,00,000)

= ₹1,12,500 + 30/100 × 335000

= ₹2,13,000

(ii) Mr. Khan is 65 years of age and his taxable income is Rs. 4,50,000.

Ans:

Taxable income = ₹4,50,000

= 5/100 (1,50,000)

= ₹7500

(iii) Miss Varsha (Age 26 years) has a taxable income of Rs. 2,30,000.
