Question

if numerator of a number is increased by 50% & denominator increased by 200%,the resultant fraction is 5/12. what is the original fraction? 

Answer 1

let the fraction be $\frac{x}{y}$
$\frac{x+ \frac{50x}{100} }{y+ \frac{200y}{100} }=\frac{1.5x}{3y}= \frac{5}{12}$
$\frac{x}{y} = \frac{5}{6}$

Answer 2

NUMERATOR IS INCREASED BY 50%=1.5X
DENOMINATOR IS INCREASED BY 200%=2Y
SO
2.5X/3Y=5/12
X/Y=5*3/12*2.5
X/Y=2/4=1/2
