80% the total number of cars sold by dealers B and E in April is what percent less than the total number of cars sold by the dealers C and D in February?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 17.5%

80% the total number of cars sold by dealers B and E in April = (580 + 740) × 80% = 1056.

Total number of cars sold by dealers C and D in February = 635 + 645 = 1280.

Required % = (1280 - 1056)/1280 × 100 = 17.5 %.
