The average monthly income of P and Q is ₹ 20000. The average monthly income of Q and R is ₹ 40000. Monthly income of R is how much more than monthly income of P?
Total income of P and Q = $$P+Q=Rs.$$ $$40,000$$ --------(i)
Similarly, $$Q+R=Rs.$$ $$80,000$$ ---------(ii)
Subtracting equation (i) from (ii), we get :
=> $$R-P=Rs.$$ $$40,000$$
=> Ans - (A)
