Question

One- fourth of a number added to two-seventh of it gives 135; Find the number.​

Answer 1

Answer:

The number=252

Step-by-step explanation:

Let the number be X

Its one fourth= 1/4x

Its two seventh= 2/7x

1/4x+2/7x=135

On cross multiplying,

7x/28+8x/28=135

15x=135*28

15x=3780

x=3780/15

x=252

Answer 2

Answer:

Step-by-step explanation:

Let the number be = x

ACQ;

1/4x + 2/7x = 135

Take the x in common

x (1/4 + 2/7) = 135

Take LCM of 4 and 7 i.e. 28

x (7+8/28) = 135

15x/28= 135

Leave the x on LHS and take the left over digit on RHS, dividing it to 135

x = 135 ÷ 15/28

x = 135 × 28/15

x = 9 × 28

x = 152
