Question

The ages of A and B are in the ratio 6 : 5. If A's age is 18 years, find the age of B
​

Answer 1

Answer:

15

Step-by-step explanation:

let the ratio be 6x & 5x

A's age =18

6x=18

x=18/6

x=3

therefore 5x=3×5=15

Answer 2

Answer:

here A's age is 6x = 18years

                            x =18/6

                           x = 3

then B's age is 5x = 5*3 = 15years

so therefore, B's age is 15 years
