A reduction of 40% in the price of bananas would enable a man to obtain 64 more for Rs.40, what is reduced price per dozen?

Correct answer: D. Rs.3

  • A. Rs.5
  • B. Rs.4
  • C. Rs.2
  • D. Rs.3

Explanation

Let the reduced price be Rs.p per banana, so the original price was Rs.p/0.6. The extra bananas for Rs.40 are Rs.40/p - Rs.40/(p/0.6) = Rs.16/p = 64, giving p = Rs.0.25 per banana. Therefore the reduced price per dozen is Rs.0.25 x 12 = Rs.3. Students often choose Rs.5 by forgetting to convert the per-banana price into a per-dozen price.
