Question

(i) If `x = 3+ (3)/(y) + (3)/(y^(2)) + (3)/(y^(3)) + … + oo`, then, show that `y = (x)/(x-3)`. (Where `|y| lt 1`). The following are the steps involv4ed in solving the above problem. Arrange them in sequential order.
(A) `xy - 3y =x`
(B) `x=3 ((1)/(1-(1)/(y)))`
(C ) `y(x-3)= x`
(D) `x =3 ((y)/(y-1))`
A. BDCA
B. BDAC
C. CABD
D. ACBD

Answer 1

Correct Answer - B
BDAC is the sequential order of steps.
