Question

A man spent 20% of his money, then Rs. 20,000 and then 16% of the remainder. If he hadRs. 1,68,000 left, what was his original money?​

Answer 1

Let the original money be x
20% of x + 20000 + 16% of (remainder) = x-168000
x/5 + 20000 + 16(x-x/5 -20000)/100 = x-168000
x/5 + 16(4x-100000)/500 = x-188000
x/5 + 64x/500 - 1600000/500 = x-188000
164x/500 = x-184800
328x = 1000x - 184800000
672x = 184800000
x = 275000

So the ans is 2,75,000

Hope it helps
