Question

The average age of p and q is 28 years. the ratio of thier ages is 5:2. what will be the ratio of thier ages after 4 years.

Answer 1

Answer:

Step-by-step explanation:

(p + q)/2 = 28

p + q  =56  .......(1)

ratio of their ages  =  5 : 2

p = 5 x ,  q = 2 x

(1) ⇒  5 x + 2 x = 56

               7 x = 56

                  x = 8

age of p = 5 x                     age of q =  2 x

              = 5(8)  = 40                         = 2(8) = 16

after 4yrs

p:q  = 44 : 20

     = 11 :  5
