Study the following table and answer the questions.

Number of machines (in thousands) sold by dealers A, B, C, D and E during six months of 2022.

80% of total no. of machines sold by dealers B and E in April is what percent less than the total no. of machines sold by dealers C and D in February?

17.5%

Sale of (B and E) in April = 580 + 740 = 1320

80% of sale of (B and E) in April = 1320 × \(\frac{4}{5}\) = 1056

Sale of (C and D) in Feb. = 635 + 645 = 1280

Required % = \(\frac{1280\;-\;1056}{1280}\) × 100 = 17.5%
