How many two digit numbers are divisible by 4?

Answer»

List of two digit numbers divisible by 4 is 

12, 16, 20, 24, . . . , 96. 

Let’s find how many such numbers are there.

tn = 96, a= 12, d = 4 

From this we will find the value of n. 

tn = 96, By formula, 

96 = 12 +(n - 1) x 4 

 = 12 + 4n - 4 

4n = 88 

n = 22 

There are 22 two digit numbers divisible by 4.
