Question

A is 15 year older than B. if the sum of ages of both is 135 year what is the age of A

​

Answer 1

Answer:

A=75, B=60

Step-by-step explanation:

A=B+15

A-B=15              -Eq(1)

A+B=135           -Eq(2)

adding Eq(1) and Eq(2):

2A=150

A=75

putting value of A in Eq(1):

75-B=15

B=75-15

  =60

Therefore, A=75 and B=60
