reena is6 years older than her brother ajay. the sum of their ages is 28 years. what are their present ages

Ajay's age = *x* years

Reena's age = *x + *6 years

Sum of their ages = 28 yrs

So, we have

*x + *(*x + *6) = 28 …………….(i)

2*x** + *6 = 28

2*x* = 28 - 6

2*x* = 22

*x* = 11

Thus, Ajay's age 11 yrs.

Reena's age = *x* + 6 = 11 + 6 = 17 yrs
