SET-5
There are nine children sitting in a 3x3 grid shown in the figure. Every child has three packets of money with him.
And in every packet, there are one rupee coins only.
Therefore, there are nine packets in every row and column. Average amount of money kept in nine packets in any
row or in any column is an integer. It is also known that total money with the child sitting in 3rd row and 1st
column is Rs.4.
Apart from that, maximum and minimum amount of money kept among three packets of every child is also given
in the given table. For example, among the three packets with the child sitting in the third column of the second
row, the minimum amount is Rs.6 and maximum amount is Rs.21.
