Three consecutive integers are such that when they are taken in increasing order and multiplied by 3,4,5 respectively,they add up to 386.Find these numbers. |
Let the consecutive numbers be x, x +1 and x + 2 Multiplied by 3, 4, and 5 respectively, The numbers will become 3(x) = 3x 4(x + 1) = 4x + 4 5(x + 2) = 5x + 10 Sum of these numbers = 386 3x + 4x + 4+ 5x + 10 = 386 12x + 14 = 386 12x = 386-14 x = 31 So numbers are 31,32,33. |
