Question

Melons father age is 5 less than 4 times his age find the father's age of melons age in K years

Answer 1

Answer:

Let Arvind's age = x

Let Arvind's father age = y

Thus, y=4x

and, y−5=7(x−5) or y=7x−30

Thus, 4x=7x−30

3x=30 or x=10

Hence, y = 40 years

Thus, age of Arvind's father is 40 years.
