Question

What is the value of $\frac{a + b}{a - b}, If \frac{a}{b} = 4$ ?

(a) $\frac{3}{5}$
(b) $\frac{5}{3}$
(c) $\frac{4}{5}$
(d) $\frac{5}{4}$

Solution

(b) $\frac{5}{3}$
$\frac{a}{b} = 4 a = 4 b On putting the value o f a in \frac{a + b}{a - b}, we get : \frac{a + b}{a - b} = \frac{4 b + b}{4 b - b} = \frac{5 b}{3 b} On dividing the numerator & denominator b y b, we get \frac{5}{3} .$
