Answer 1

Answer:

28 hoga bhai

Step-by-step explanation:

in between 100 3 and in between 100 to 900 31 divisible by either 2 3 5

so 31-3=28

Answer 2

Given:

range: 100 to 900

To find:

Number of whole numbers divisible by 2, 3, 5.

Solution:

2, 3 and 5 are prime numbers.

So, numbers that are divisible by 2, 3 and 5 should also be completely divisible by 2×3×5 = 30.

But according to the given statement, we must exclude 100 and 900. So, we must consider the numbers from 101 to 899.

So numbers between 101 and 899 that are completely divisible by 30 are as follows:

120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480, 510, 540, 570, 600, 630, 660, 690, 720, 750, 780, 810, 840, 870.

There are a total of 26 whole numbers between 100 and 900 that are divisible by 30.

We can also calculate the same by$=\frac{800}{(2)(3)(5)}=26$

Hence, 26 numbers are 2, 3 and 5 between 100 and 900, excluding 100 and 900.
