Question
Given set: 278, 257, 365
In the following question, choose one number which is similar to the numbers in the given set.Solution
In all the numbers, the middle digit is the sum of the digits of the product of other two digits. 278 = 2 x 8 = 16, 1 + 6 = 7 257 = 2 x 7 = 14, 1 + 4 = 5 365 = 3 x 5 = 15, 1 + 5 = 6 337 = 3 x 7 = 21, 2 + 1 = 3
