# Find Out the Number, If

If the sum of two numbers, one of which is 2/5 times the other is 50, then the numbers are:

- 11/7, 235/7
- 150/7, 22/7
- 240/7,110/7
- 250/7, 100/7

**Answer: (4) 250/7, 100/7**

**Explanation:-
**Let the both numbers are X and Y.

According to the question,

X = 2 Y/5

X + Y = 50 …………….. (1)

Put the value of X in equation (1),

Then, 2 Y/5 + Y = 50

(2 Y + 5 Y) /5 = 50

7 Y = 50 x 5

Y = 250/7

Put the value of Y in equation (1),

X + 250/7 = 50

X = 50 – 250/7

X = (350 – 250)/7

X = 100/7

Then, the numbers are 250/7 and 100/7

Hence, the answer is (4) 250/7 , 100/7.
