Question

Two numbers are in the ratio 5: 3, if their sum is 80, then the smallest number is
a] 50
b] 30
c] 10
d] none of these​

Answer 1

Answer:

The smallest number is 30.

Answer 2

Answer:

let the common ratio is x

so the numbers are 5x and 3x

so,

5x+3x=80

=> 8x=80

=> x=80/8

=> x=10

so the smallest number is 3x=3.10=30
