AB × AC Where B + C = 10

AB × AC = A × •A / B × C (In 2 digits)

(1)

48 × 42 = 4 × •4 / 8 × 2

              = 4 × 5 / 16

              = 20 / 16

              = 20 / 16

              = 2016

In Short 

48 × 42 = 4 × •4 / 8 × 2

              = 20 / 16

              = 2016

(2)

71 × 79 = 7 × •7 / 1 × 9

              = 7 × 8 / 09

              = 56 / 09

              = 5609

In Short 

71 × 79 = 7 × •7 / 1 × 9

              = 56 / 09

              = 5609

(3)

53 × 57 = 5 × •5 / 3 × 7

              = 5 × 6 / 21

              = 30 / 21

              = 3021

In Short 

53 × 57 = 5 × •5 / 3 × 7

              = 30 / 21

              = 3021
