(b) Rs 36,000
(c) Rs 38,000
(d) Rs 42,000
(e) Rs 40,000

Answer 1

let the total income be x then

15% of x = 15x/100=3x/20

10 % of remaining = 10/100*3x/20

= 3x/200

remaining money for house expense

= 30,600

therefore,

x-3x/20-3x/200 = 30,600

200x-30x-x/200 = 30,600

169x/200 = 30,600

x= 30600 * 200/169

x = 36,213.213

therefore (b) is the answer

please mark me as brainliest!!!!
