Answers
Answer:
38% savings
Step-by-step explanation:
assuming the income to be 100rs,so the expense would be 72%,savings 28%...increase in income would be 128(28% of 100),and increase in expense would be 90(25% of 72,i.e 18)
hence ,firstly the savings wud be 100-72=28%
in second instance it would be 128-90=38%
Answer:
% increase in savings = 35.7
Step-by-step explanation:
let income = 100
ATQ
if he spends 72% of his income, then
Expenditure = 72
Savings = 28
if his income increases by 28%, then exp. increases 25%, i.e.
Income = 128%of100 = 128
Expenditure = 125% of 72 = 90
Savings = 128-90 = 38
Therefore increase in savings = 38-28 =10
% increase in savings = (10/28)*100
= 35.7
