If (frac{x}{a+1}+frac{y}{b}) 1. Make y the subject of the relation

If (frac{x}{a+1}+frac{y}{b}) 1. Make y the subject of the relation
  • A.
    (frac{b(a-x+1)}{a+1})
  • B.
    (frac{a+1}{b(a-x+1)})
  • C.
    (frac{a(b-x+1)}{b+1})
  • D.
    (frac{b}{a(b-x+1)})
Correct Answer: Option A
Explanation

If (frac{bx+y(a+1)}{b(a+1)}=1\
bx + ya + y = ba + b; y(a+1) = ba+b-bx\
y(a+1)=b(a+1-x); y = frac{b(1+a-x}{a+1})
