Question

The ratio of the age of 3 people p q and r is 6:7:11 if the sum of p and r is 102 years find age of q

Answer 1

Age of q = 42 years

Explanation:

Ratio of the ages of three people p, q and r is 6 : 7 : 11

Sum of the ages of p and r = 102 years

Age of p =
`(6)/((6+11))* (102)`

= 36 years

Therefore, age of r = 102 - 36

= 66 years

Since, ratio of p and q = 6 : 7

Therefore,
`\frac{\text{Age of p}}{\text{Age of q}}=(6)/(7)`

`(36)/(q)=(6)/(7)`

q =
`(36* 7)/(6)`

q = 42 years
