1. Find the number which when multiplied by 4 is increased by 39.

Solution:

                  Let the number be x.

                  4x= x+39

                  3x=39

                   x=13

The required number is 13.

2. If a number, when divided by 3, is reduced by 12. Find the number.

Solution:

                  Let the number be x.

                  x/3 = x-12

                  x = 3x-36

                  2x=36

                  x=18

The number is 18.

3. The third part of a number is decreased by 8 which is equal to the sixth part of the number increased by 2. Find the number. 

Solution:

                  Let the number be x.

                  (x/3)-8 = (x/6)+2

                  (x/3)-(x/6) = 10

                  (2x-x)/6 = 10

                   x/6 =10

                   x = 60

The number is 60.
