Question

The sum of the reciprocal of two consecutive odd natural number is 12/35 .find those numbers

Answer 1

Answer:

The two numbers are 5 and 7.

Step-by-step explanation:

Let, the two consecutive integers be x and x+2.

ATQ,

1/x + 1/x+2 = 12/35

35(x+2) + 35x = 12x(x+2)

35x+70+35x=12x^2 + 24x

70x+70=12x^2 + 24x

12x^2 + 24x - 70x -70 = 0

12x^2 + 46x - 70 = 0

By factoring, we get;

x=5 and -7/6

We ignore -7/6, because it is a negative number.

Therefore, x=5

and, x+2 = 5+2 = 7

Therefore, the two numbers are 5 and 7.
