Question
The ratio of the incomes of P, Q, and R is 3:5:6. If
P’s income is increased by 25%, R’s income is increased by 15%, and Q’s income is reduced by 30%, the difference between the new incomes of R and P becomes ₹945. What was Q’s original income?Solution
Let their original incomes be 3z, 5z, and 6z Income of P after a 25% increase = 3.75z Income of Q after a 30% decrease = 3.5z Income of R after a 15% increase = 6.9z 6.9z – 3.75z = 945 3.15z = 945 z = 300 Q’s original income = 5z = ₹1,500
