1.

The sum of the digits of a 2-digit number is 12. The number is 6 times the units der Find the met

Answer»

Let the unit digit be x then ten digit = (12-x)

Then,Number = 10*(12 - x) + x= 120 - 9x

As per given condition120 - 9x = 6x9x + 6x = 12015x = 120x = 120/15 = 8

Therefore,Number = 120 - 9*8= 120 - 72= 48
