A175000

B105000

C125000

D135000

Answer:

A. 175000

Read Explanation:

ratio of weights = 1 : 2 : 3 : 4 1 + 2 + 3 + 4 = 10 Its value varies directly with the square of its weight ⇒ ratio = 1 : 4 : 9 : 16 1 + 4 + 9 + 16 = 10^2 = 100 ⇒ 30 = 100 100 = 250000 100 - 30 = 70% = 250000 × 70/100 = 175000
