Answer 1

Hi friend,

# 28%

Solution:-

Savings = income - expenditure

13500 - 9,000 = 4,500

His income increased by 14%

So,13,500*(14/100) = 1,890

His expenditure increased by 7 %

So, 9,000 * (7/100) = 630

New savings = 1,890 -630 = 1,260

Percentage increased by this savings :-

1,260 * (100/4,500) = 28%

Thus, the percentage increased in his savings is 28%...i hope it helps you
