Question

3) Ajay is younger than Vijay by 7 years. The sum of their ages is 53 years.
What is Vijay's age?
​

Answer 1

Answer:

let's x be the ajay age

and y be the Vijay age

by given condition

x=7+y

x-y=7------------1

by second condition

x+y=53-----------2

Now,

eqn 1+2→

x-y=7

+

x+y=53

________

2x=60

x=60/2

x=30

Now,

put x=30 in eqn 2

x+y=53

30+y=53

y=53-30

y=27
