If I explain a little bit about my approach.Then first find the sum of 1 to 15 which is 120.Then divide it by 3 because there is 3 row so we can conclude that each row will have a sum of 40.Try filling with the random number to get the sum of 40 in each row.Fill first two rows then write the remaining number in the third row it will sum up to 40 by default.
