-3 by -5

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Correct option is

A

2113

Suppose numerator of the rational number is p, then denominator is p+8.

Rational number is p+8p.

Numerator is increased by 17, then it becomes p+17.

Denominator is decreased by 1, then it becomes p+8−1=p+7

New rational number is p+7p+17=23

⇒2p+34=3p+21

⇒p=13

Thus numerator is 13.

Denominator is p+8=13+8=21

Therefore, the rational number is 2113.
