IBPS PO Prelims Model Paper 15

2) Let Sneha’s age be x yrs
Deep’s age = 48-x yrs
let Rohan’s age be y yrs
According to ques.,
Deep's age = 4 + Rohan's age
i.e., 48 - x = 4 + y
x + y = 44 ← 1
Also,

x

y

=

7x - 4y = 0 ← 2
Multiply eq.1 by 4
4x + 4y = 176 ← 3
solving eq. 2 & 3 we get,
x=

176

y = 28
Hence, Deep’s present age
= 4 + y = 4 + 28 = 32 years
Deep’s age 2 year ago = 30 years
