Question

A man spend 1800 per month and save 25% of his income his monthly income is

Answer 1

Given that man saves 25% , which means men spend 100 - 25 = 75%

given that man spend = Rs 1800

So 75% of mans income = Rs 1800

so 1% of mans income= 1800/75

hence 100% of mans income = (1800/75) × 100  = Rs 2400

hence mans income = Rs 2400

Answer 2

let the monthly income be 'x'

percentage he saves=25%

percentage he spends=100%-25%= 75%

75%x=1800

3/4x=1800

x=1800*4/3

x=600*4

x=2400

the monthly income of a man is Rs. 2400
