Question

The ratio of income and expenditure of a person is 4 : 3. If income is increased by 20% and expenditure is decreased by 10% then what is the percentage increase or decrease in the savings?

Answer 1

Answer:

110%

Explanation:

income/expenditure = 4/3

income = expenditure+ savings

4x = 3x+savings

x = savings

income increased by 20% and expenditure decrease by 10%

4x+4x/5 = 3x-3x/10+savings

savings =x+11x/10

which is 110% more than x
