CMAT 2020 · Quantitative Techniques & Data Interpretation · Medium · Arithmetic

A city has an average demand of water of 33,000 Lts. of water which lasts for 50 days. But if some people enter the city, then the demand increases to 37,000 Lts. of water for which supply will lasts 35 days. Give an estimation of how much minimum water should be used daily so that it could last 50 days ?

  1. A.

    24,253.00 Lts.

  2. B.

    23,666.66 Lts.

  3. C.

    23,662.34 Lts.

  4. D.

    24,123.72 Lts.

Answer

B

Explanation

Total water capacity = 33000×50=1,650,00033000 \times 50 = 1,650,000 Lts.

Water consumed in 35 days at increased demand = 37000×35=1,295,00037000 \times 35 = 1,295,000 Lts.

Remaining water for the remaining 15 days = 1650000−1295000=355,0001650000 - 1295000 = 355,000 Lts.

Daily limit for remaining 15 days = 35500015=23666.66\frac{355000}{15} = 23666.66 Lts.
