Answer 2

Answer:

option c is correct answer.

Explanation:

In first case,

X = g/ 2( 2n-1) ( according to the formula)

or, 2X = g( 2n - 1)

or, (2X / g) + 1 = 2n ( eqn. 1)

In 2nd case,

Y = g/2(2n + 1)

or,( 2Y / g )-1 = 2n ( eqn.2)

Now, eqn.1 = eqn.2

so(, 2x/ g) +1 = (2Y / g)- 1

or, 2 g = 2Y - 2X

or, g= Y- X( answer C )
