Answer : Option C
Explanation :
Rakesh +Suresh (total income) = 5050 x 2 = 10100.... (i)
Suresh +Ramesh (total income) = 6250 x 2 = 12500.... (ii)
Rakesh+ Ramesh (total income) = 5200 x 2 = 10400.... (iii)
Adding (i), (ii) and (iii), we get: 2(P + Q + R) = 33000 or P + Q + R = 16500.... (iv)
Subtracting (ii) from (iv), we get P = 4000.
So, Rakesh's monthly income = Rs. 4000.
