Study the following table and answer the question:
Number of cars sold by dealers A, B, C, D & E during first six months of 2018.

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?

17.5%

80% the total number of cars sold by dealers B and E in April

= \(\frac{4}{5}\) × ( 580 + 740 )

= 1056

Total cars sold by C & D in february = 635 + 645 = 1280

Required percentage= \(\frac{1280 - 1056}{1280}\) ×100

= \(\frac{224}{1280}\) × 100

= 17.5%
