Sonia earned Rs. 29000 every month and spent Rs. 21000. In
the following year, her income went up by 13% and her expenditure increased by 6%. What is the percentage rise in her savings?Solution
ATQ,
Initial savings = 29000 – 21000 = Rs. 8000
New income = 1.13 Ă— 29000 = Rs. 32770
New expenses = 1.06 Ă— 21000 = Rs. 22260
New savings = 32770 – 22260 = Rs. 10510
Percentage increase = [(10510 – 8000)/8000] × 100 = 31.38%
