A) Rs. 2000	B) Rs. 3000	C) Rs. 4000	D) Rs. 4500	E) Rs. 5000
Let P, Q and R represent their respective monthly incomes. Then, we have:   P + Q = (5050 x 2) = 10100 .... (i)   Q + R = (6250 x 2) = 12500 .... (ii)   M + O = (5200 x 2) = 10400 .... (iii)   Adding (i), (ii) and (iii), we get: 2(M + N + O) = 33000 or M + N + O = 16500 .... (iv)   Subtracting (ii) from (iv), we get M = 4000.   M's monthly income = Rs. 4000   Rs. 4000
