Correct Answer: K


Solution : Given:
(I)  Among five objects E, F, G, H, and K, the weight of H is 3 times the weight of K.
H = 3K
(II) The weight of G is 7.5 kg.
G = 7.5kg
(III) The weight of E is twice the weight of F.
E = 2F
(IV) The weight of K is 4 times the weight of G.
K = 4G
(V) If the weights of F and G are equal.
F = G
Now according to the given instructions:
K = 4G = 4 × 7.5 = 30 kg, H = 3K = 3 × 30 = 90 kg, F = 7.5 kg, E = 2F = 2 × 7.5 = 15 kg
⇒H > K > E > F = G

So, K is the second heaviest object. Hence, the first option is correct.
