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

Age of q = 42 years

Step-by-step 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 =

               = 36 years

Therefore, age of r = 102 - 36

                                = 66 years

Since, ratio of p and q = 6 : 7

Therefore,

q =

q = 42 years
