Question

A man saves Rs. 32 during one month Rs. 36 next month and so on increasing his monthly savings at the rateofRs.4 per month. Find the number of months he will take to save Rs.2000.

Answer 1

Answer:

I think you can solve it with the help of A.P. (Arithmetic progression)

so, let the no of months he will take to save 2000 money be n

therefore,

a = 32

d = 4

l = 2000

al = a + (n - 1) x d

=> 2000 = 32 + ( n-1) x 4

=> 2000 - 32 = (n - 1) x4

=> 1968 = ( n-1) x 4

=> 1968/4 = n-1

=> 492+1 =n

n = 493

in 493 months he will have 2000 rupees

Answer 2

so, answer is 25 months
