Question

1.b) plese fast answer​

Answer 1

Answer:

15

or divide by 5

.

On dividing x

by five, we get x5

.

Now, four has to be subtracted from the one fifth of the unknown number. On subtracting four from x5

, we get (x5−4)

.

We will now equate the above expression to 3, so that we can write the mathematical equation as:

x5−4=3

Adding 4

on both the sides, we get

⇒x5=7

On multiplying both the sides by 5

, we get

⇒x=35

Therefore, the value of the required number is 35.
