Question
If M and L have 19 and 28 medals respectively, then O
may have ___ medals. Answer the questions based on the information given below: Six persons J, K, L, M, N and O have different number of medals. K has more medals than J. J has more medals than at least 2 persons. Three persons have more medals than M. O has fewer medals than N. L has more medals than N. L has fewer medals than J.Solution
Three persons have more medal than M, so __ > __ > __ > M > __ > __ K has more medals than J. J has more medals than at least 2 persons. O has fewer medals than N. L has more medals than N. L has fewer medals than J, so K > J > L > M > N > O As O has least number of medals, so O may have 16 medals.
