Correct Answer - Option 1 : 180
Six persons: P, Q, R, S, T and W.
1) The weight of the second heaviest person is 120 kg.
2) Weight of T is 120. Imply that T is the second heaviest person.
The possible arrangement for the given statements is as follows,
___ > T(120) > ___ > ___ > ___ > ___
3) Only two persons have weight more than P.
4) Sum of the weight of S and T is 250 kg.
S + T = 250
S + 120 = 250
S = 250 - 120 = 130
S(130) > T(120) > P > ___ > ___ > ___
5) the weight of the second lightest person is 78 kg.
6) R is heavier than both W and Q but W is not the lightest. It means W is the second lightest having weight 78 kg.
7) Sum of the weight of W and Q is 128 kg.
W + Q = 128
78 + Q = 128
Q = 128 - 78 = 50
The final arrangement is as follows,
S(130) > T(120) > P > R > W(78) > Q(50)
Sum of the weight of S and Q = 130 +50
180.
Hence, sum of weight of S and Q is 180.
