Answer 1

Step-by-step explanation:

According to given data we have,

Let S1 & S2 denote the monthly rate of savings from monthly-incomes over the periods of 16 months & 14 months respectively.

Hence the purchase price of the car = 16*S1 = 14*S2

or S2 = (8/7)*S1 = (1 + 1/7)*S1

or S2 = (1 + 0.14286)*S1 = (1 + 14.286/100)*S1

Therefore, the required percentage of increase in the savings to purchase the same car in 14 months only = 14.286% [Ans]
