Among the boxes, A, B, C, D and E. B is twice as heavy as A. C is 20 kg heavier than E. D is one and a half times as heavy as E, and C is four times as heavy as A. The weight of E is 20 kg. Which object is the heaviest of all. and what is its weight ? Correct Answer C, 40 kg

According to the given information:

B is twice as heavy as A

B = 2 × A

C is 20 kg heavier than E

C = 20 + E

D is one and a half times as heavy as E

D = 1.5 × E

C is four times as heavy as A

C = 4 × A

A = C ÷ 4

Weight of E is 20 kg

E = 20 kg

C = 20 + 20 = 40 kg

D = 1.5 × 20 = 30 kg

A = 40 ÷ 4 = 10 kg

B = 2 × 10 = 20 kg

So, the ascending order of the weight of the objects is:

A < B = E < D < C

Hence, the heaviest object is "C, 40 kg".
