There are four numbers, from which three numbers are taken at a time and added together to get four sums, which are 22, 24, 27 and 20 respectively

There are four numbers, from which three numbers are taken at a time and added together to get four sums, which are 22, 24, 27 and 20 respectively

Among the four sums, each of the four numbers appears three times
The sum of four numbers: (22 + 24 + 27 + 20) △ 3 = 31
The four numbers are as follows:
31-22=9
31-24=7
31-27=4
31-20=11
