Question

How many two digit numbers leave the remainder 1
when divided by 5​

Answer 1

ANSWER :

A = 11

An = 96

D = 5

n =?

We know that,

An = A + (n - 1) D

96 = 11 + (n - 1) 5

96 - 11 = (n - 1) 5

85 / 5 = n - 1

17 = n - 1

n = 17 + 1 = 18

Therefore 18 two digit numbers leave the remainder 1 when divided by 5
