Answer 1

a number when divided by 4 HD

Answer 2

Answer:

28

Step-by-step explanation:

When we get to solve such questions, then the first step must be to assume our answer as a variable like ' x '.

So, Let the required number be ' x ' .

If we read the question carefully then on the basis of our assumption we can derive the following equation,

x / 4 = x - 21

Now taking ' x ' on RHS to LHS,

x / 4 - x = - 21

( x - 4x ) / 4 = - 21

Taking " /4 " on LHS to RHS,

- 3x = - 21 * 4

- 3x = - 84

Cancelling the negative signs,

3x= 84

Taking " 3 " on LHS to RHS,

x = 84 / 3

x=28

Hence, The required number = x = 28
