Solution

The problem is about finding the monthly income of P. We can solve this problem using the concept of averages. Here are the steps:

  1. The average monthly income of P and Q is Rs. 5050. This means the total income of P and Q is 2*5050 = Rs. 10100.

  2. The average monthly income of Q and R is Rs. 6250. This means the total income of Q and R is 2*6250 = Rs. 12500.

  3. The average monthly income of P and R is Rs. 5200. This means the total income of P and R is 2*5200 = Rs. 10400.

  4. If we add the total income of P and Q (Rs. 10100) and the total income of Q and R (Rs. 12500), we get Rs. 22600. This is the total income of P, Q, Q and R.

  5. If we subtract the total income of P and R (Rs. 10400) from this, we get Rs. 22600 - Rs. 10400 = Rs. 12200. This is the total income of P and Q.

  6. Since P and Q have the same total income, the monthly income of P is Rs. 12200 / 2 = Rs. 6100.
