You have 2 positive numbers. One number is one-fifth of the other number. The difference between the two numbers is 312, find the numbers.

Mr China and Russia at war in 629

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
