Detailed Explanation & Answer

Savings = Income - Expenditure

Savings for 2020,
= Rs 65,000 - Rs 45,000 = Rs 20,000
In 2021,
Income = 65000 x 115 / 100 = 74,750
Expenditure = 45000 x 107 / 100 = 48,150
Savings = Rs 74,750 - Rs 48,150 = Rs 26,600

Increase in Saving = 26600 = 20000 = 6600
Which is 6600 / 20000 x 100 = 33% of increase

बचत = आय - व्यय

2020 के लिए बचत,
= 65,000 रुपये - 45,000 रुपये = 20,000 रुपये
2021 में,
आय = 65000 x 115/100 = 74,750
व्यय = 45000 x 107/100 = 48,150
बचत = 74,750 रुपये - 48,150 रुपये = 26,600 रुपये

बचत में वृद्धि = 26600 = 20000 = 6600
जो कि 6600/20000 x 100 = 33% वृद्धि है
