Question

Mr Sahai and his wife are both school teachers and earn Rs 16800 and Rs 10500 per month respectively. Find the ratio of
(i) Mr Sahai's income to his wife's income;
(ii) Mrs Sahai's income to her husband's income;
(iii) Mr Sahai's income to the total income of the two.​

Answer 1

Answer:

Mr Sahai's earning = Rs 16800

Mrs Sahai's earning = Rs 10500

(i) Ratio = 16800:10500 = 168:105 = 168 ÷ 21 = 8 (H.C.F. of 168 and 105 is 21.)

105 ÷ 21 5

Mr Sahai's income:Mrs Sahai's income = 8:5

(ii)Ratio = 10500:16800 = 105:168 = 105 ÷ 21 = 5 (H.C.F. of 168 and 105 is 21.)

168 ÷ 21 8

Mrs Sahai's income:Mr Sahai's income = 5:8

(iii) Total income = 16800 + 10500 = Rs 27300

Ratio = 16800:27300 = 168:273 = 168 = 168 ÷ 21 = 8 (H.C.F. of 168 and 273 is 21.)

273 273 ÷ 21

= 13

the ratio of Mr. Sahai's income to his wife' income is 8:5.
