Explanation :

Total = 16000

35% of the total products are product B

Total products of B type = 35% 16000 = 5600

Ratio of plastic and metallic products in product B is 4:3

Plastic products of product B = 4/7 * 5600 = 3200

Metallic products of product B = 3/7 * 5600 = 2400

Plastic products of product A = 110% (number of plastic products of product B)

= > 110 % 3200 = 3520

Ratio of metallic products of product C and the number of plastic product of product A is 3:5 respectively

Metallic products of product C = 3/5 * 3520 = 2112

Number of Metallic products of product A = 80% of 2400 =1920

Total products of B = 5600

Total products of A = 3520 + 1920 = 5440

Total Products of C = 16000 – (5600 + 5440) = 4960

Total Plastic products of Product C = 4960 – 2112 = 2848

1) Answer: D

Difference between the number of plastic materials and the number of metallic materials of product C

= 2848 – 2112

=736

2) Answer: C

Required Ratio = 1920: 2400 = 4:5

3) Answer: E

Total = 5440 + 5600 = 11040

4) Answer: A

Number of plastic materials of product A = 3520

Total product of B = 5600

Required percentage = (3520 / 5600) * 100= 62.85 % ≈ 63%

5) Answer: E

Difference = 3200 – 1920= 1280
