Given:

One number

= \frac{2}{5} \times

another number

Calculation:

Let one number be a then the other number is b

It is given that number

b

\frac{2}{5}^{\text{th }}

times of a

Therefore, b = 0.4a

Then according to the question,

a + 0.4a = 50

⇒ 1.4a = 50

⇒ a

= \frac{250}{7}

and

∴ The other number is $\frac{100}{7}$
