Question

what least value must be assigned to *, so that the number 6912*is divisible by 25?

Answer 1

25 = 5*5

Divisibility Rule by 5 = last digit is 5 in the number

so 5 is least number

Answer 2

Answer:

5

Step-by-step explanation:

Given : The number 6912*is divisible by 25

To Find : What least value must be assigned to *, so that the number 6912*is divisible by 25?

Solution:

The number 6912*is divisible by 25

Multiples of 25 has 0 or 5 in the unit place

So, * must be 0 or 5

Let us suppose * is 0

So, number = 69120

So, $\frac{69120}{25}=2764.8$

So, 69120 is not completely divisible by 25

Let us suppose * is 5

So, number = 69125

So, $\frac{69125}{25}=2765$

So, 69125 is completely divisible by 25

Hence the least value must be assigned to *, so that the number 6912*is divisible by 25 is 5
