Question

how many multiply of 5 is between 10 and 250​

Answer 1

Answer:

68 multiples

Step by step explanation:

First find the number of multiples of 5 in between 1 to 50 and between 1 to 250.

No. of multiples between 1 and 10= 2

No. of multiples between 1 and 250= 70

∴Multiples of 5 between 10 and 250= 70-2 =68

Answer 2

Clearly, the numbers between 10 and 250 which are multiple of 4 are 12,16,20,...,248.

This is an AP with first term a=12, common difference d=4.

Let there be n terms in this AP, then an = 248

⇒ a+(n−1)d = 248

⇒ 12+(n−1)×4 = 248

⇒ (n−1) = 59

⇒ n = 60
