# What will be The First Number? If

The sum of three numbers is 392. The ratio of first and second number is 2:3 and that of second and third number is 5:8. Then the first number is

- 100
- 80
- 120
- 60

**Answer: (2) 80**

**Explanation:-
**The ratio of first and second numbers = 2: 3

The ratio of second and third numbers = 5: 8

Then, the ratio of first, second and third numbers = 2 x 5: 3 x 5: 3 x 8

= 10: 15: 24

The sum of the three numbers = 392

Then, 10X + 15X + 24X = 392

59 X = 392

X = 392/59

X = 8

Then, the value of first number is 10X = 10 x 8 = 80

Hence, the answer is (2) 80.
