A person buys three articles P, Q and R for Rs 3,330. If P costs 25% more than R and R costs 20% more than Q, then what is the cost of P?
  1. Rs 1,000
  2. Rs 1,200
  3. Rs 1,250
  4. Rs 1,350

Solution

Let Q = 100. Then R = 120% of 100 = 120, and P = 125% of 120 = 150. So P : Q : R = 150 : 100 : 120 = 15 : 10 : 12, total 37 units = Rs. 3330, so 1 unit = Rs. 90. Hence P = $15 \times 90 = $ Rs. 1350.
