Ramesh and Suresh have a total of Rs 200. If Ramesh gives Rs 40 to Suresh, then the amounts with both would get interchanged. Find the amount with Suresh (in Rs)

Options

A. 70
B. 60
C. 50
D. 80

Answer

d

Explanation

Let the amount with Ramesh and Suresh be Rs R and Rs S, respectively.
`R + S = 200` (1)
If Ramesh gives Rs 40 to Suresh, then Ramesh would have Rs `(R -40)` and Suresh would have `Rs S + 40`
The amounts with both would then get interchanged.
`:.R - 40 = S and S + 40 = R`
These equations are the same. solving one of these along with Eq. `(1), R = 120 and S = 80`.
Hence, the correct option is (d)
