Question

How many numbers between 55 and 555 including both the extreme values are divisible by 5?

Answer 1

$\textbf{Answer}$

Lets calculate total numbers between 55 and 555.

Total numbers between 55 and 555 = 555-55

=> Total numbers between 55 and 555 = 500

Since we have to calculate the total numbers from from 55 to 500 which are divisible by 5,
The numbers we want os to be calculated in this way-
$\textbf{55,60,65,70,75,80,........555}$

Since numbers are multiples of 5,
And we need to include the extreme values 55 and 555 in the answers,

Total multiples of 5 will be as calculates as,

$\textbf{(500/5) + 1}$
= 100 + 1
= 101

So $\textbf{101 numbers between 55 and 55}$ are $\textbf{divisible by 5.}$

Answer 2

the series is 55, 60, 65,...........,555

first number is 55

last number is 555

no of terms = (last number - first number)/5 + 1

no of terms = (555-55)/5 + 1

no of terms = 500/5 + 1

no of terms = 100 + 1 = 101

no of terms between 55 and 555 including both ends is 101
