Question

how many multiples of 5 lies between 50 an 250

Answer 1

There are 40 multiples between 50 and 250

49 is not the correct ans

Answer 2

There are 40 multiples of 5 in between 50 and 250

Solution:

Given, lower range = 50 and higher range = 250.

We have to find the number of multiples of 5 in that range.

Now, first let us find number of multiples of 5 in between 1 to 50 and between 1 to 250.

Then, after subtracting number of multiples between 1 to 50 from 1 to 250, gives our required answer.

So, 5 multiples between 1 to 50 $= \frac{50}{5} = 10$

Now, 5 multiples between 1 to 250 $= \frac{250}{5} = 50$

Then, number of multiples of 5 between 50 and 250 = 50 – 10 = 40.

Hence, there are 40 multiples of 5 in between 50 and 250.
