(#M40000252) GMAT QUESTION Keep an EYE

A man spends 75% of his income, when his income is increased by 20%, he increases his expenditure by 10%. By how much per cent are his savings increased

Solution

Let the income of the man = x
then expenditure = 0.75x and savings = 0.25x
now after 20 % increment income = 1.2x and with 10 % increment in the expenditure it will be 0.75x*1.1 = 0.825x
so savings = 1.2x - 0.825x = 0.375x
so new % of savings relative to new income = (0.375x/1.2x)*100
= 0.3125*100 = 31.25 %
