Q1. The average monthly income of P and Q is Rs. 5,050. The average monthly income of Q and R is Rs. 6,250. The average monthly income of P and R is Rs. 5,200. What will P's monthly income be?
Answer: Rs. 4000
Explanation: P+Q = 10100, Q+R = 12500, P+R = 10400; total 2(P+Q+R) = 33000, so P = 16500 − 12500 = Rs. 4000.
