Obtain all pairs of consecutive odd natural numbers such that in each

1.	Obtain all pairs of consecutive odd natural numbers such that in each pair both are more than 50 and their sum is less than 120.
Answer» Taking the pair as x, x + 2, we get x > 50, 2x + 2 < 120 ⇒ x < 59 and writing the required pairs are (51, 53), (53, 55), (55, 57), (57, 59).

Obtain all pairs of consecutive odd natural numbers such that in each pair both are more than 50 and their sum is less than 120.
