Question

Reena is 6 year older than her brother ajay if the sum their ages is 28 years what are their presents age

Answer 1

Let Rina's brother age=x

Then, Rina's age=x+6

A/Q,

x+x+6=28

2x=28-6

x=22/2

x=11

Then, Rina's brother age=x=11

And Rina's age=x+6=11+6=17

I hope it's working for you

Answer 2

Let Reena's age be 'x'

Let Ajay's age be 'y'

According to question,

x - y = 6          ...|| eq i

x + y = 28         ...||eq ii

adding eq i & ii we get

2x = 34

x = 17          ...|| eq iii

putting eq iii in i

y = 11

present ages of Reena and Ajay are 17 & 11 respectively
