# Two numbers are in ratio 5:8. If their difference is 48, then the smallest number is :

**Answer is 80.**

**Explanation:-**

The ratio of two numbers = 5: 8

Let the two numbers be 5 X & 8 X

If their difference is 48,

8 X – 5 X = 48

3 X = 48

X = 48/3

X = 16

Then, the two numbers are 5 X = 16 x 5 = 80 & 8 X = 16 x 8 = 128.

So, the smallest number is 80.

Hence, the correct answer is option (4) 80.
