Question

if one fifth of a number is less than its one fourth by 3 then the number is---------------

Answer 1

Let the number = x
1/5 x + 3 = 1/4 x
⇒ 1/5 x - 1/4 x = -3
⇒ 4-5 x/ 4*5 = -3
⇒ -1/20 x = -3
⇒x = 60

Answer 2

Given,

• One-fifth of a number is less than its one-fourth by 3.

To find,

• We have to find the number.

Solution,

We can simply find the number by using the given conditions.

Let the required number be 'x'

one-fifth of a number = x/5

one-fourth of a number = x/4

According to the given condition,

One-fifth of a number is less than its one-fourth by 3

        x/4 - x/5 = 3

Taking LCM, we get

       (5x-4x)/20 = 3

              x/20  = 3

By cross multiplication, we get

                    x = 3*20

                    x = 60

Hence, if one-fifth of a number is less than its one-fourth by 3 then the number is 60.
