Question

3/7 of 1/4 of 2/5 of a number is 15. then find the value of half of the same number?​

Answer 1

Answer:

The half of the number is 175.

Step-by-step explanation:

Given that 3/7 of 1/4 of 2/5 of a number is 15.

Let the number be x.

Therefore, we can write the equation as,

          3/7 × 1/4 × 2/5 × x = 15

          6/140 × x = 15

                x = 15 × 140/6 = 350

The half of the number = 1/2 of 350

                                      = 1/2 × 350 = 175
