Answer 2

Step-by-step explanation:

after 7 years prateek's age is z+7

then his grandpa's age is 5z+2+7

According to the question

z+7+5z+2+7 = 94

       6z+16   = 94

               6z = 94-16

               6z = 78

                  z = 78/6

                  z = 13

so,

Prateek's age = z = 13 years

prateek's grandfather's age = 5z+2 = 67 years
