Question

A is 20 year older than B. He is Also six times as old as B. Find their present ages?​

Answer 1

Step-by-step explanation:

A is 20 years older than B. Hence,A is x + 20 years old . A is also six time as old as B. Hence,age of A is 24 years and age of B is 4 years .

Answer 2

A = 20 + B --(1)

A = 6B

substitute A = 6B in (1)

6B - B = 20

5B = 20

therefore B = 4

Substitute B = 4 in (1)

A= 20 + 4

THEREFORE A = 24 , B = 4
