Question

A man saved rs. 32 during the 1st year rs.36 in second year and in this way he increases his saving by rs.4 every year find in what time his saving will be rs.200

Answer 1

First term,a = 32
Common difference ,d = 4
An = 200
n = number of days
An = a + (n-1)d
200 = 32 + (n-1)4
200- 32 = (n-1)4
168 = (n-1)4
168/4 = (n-1)
42 = n -1
43 = n

It will take 43 days for his saving to reach 200
