Add 1 to each number and then multiply.
Thus: 2,6 becomes 3 * 7 = 21
And 6,5 become 7 * 6 = 42

Answer is 42
Each no. is incremented 1 and multiply both no.
2,6 = 3*7 = 21
3,8 = 4*9 = 36
4,5 = 5*6 = 30
5,7 = 6*8 = 48
6,5 = 7*6 = 42

A) 2,6 =21
When you add 1 to each side and multiply the added value you arrive at the given answers (3,7=21)
B) 3,8 = 36 (4,9 = 36)
C) 4,5 =30 (5,6=30)
D) 5,7 =48 (6,8 =48)
E) 6,5 =X (7,6 =42) therefore x=42
