This is the question of data sufficiency, in which you have to decide whether the given statement is sufficient to solve the problem or not? Here in this question, we need to find ages of four persons than after we can compare who is the eldest and who is the youngest.
rnFour unknown means we need four equations:
rnbut according to the question, we have only two equations
rn1) P + Q + R + S = 45
rn2) (P+2) + (Q-2) + (2*R) + (S/2) = 45
rn
rnAfter Solving this, we have
rn1) P + Q + R + S = 45
rn2) R = (0.5*S)
rn
rnHence, data is insufficient.
