If the numerator of a certain fraction increased by 200% and the denominator is increased by 150% the new fraction thus formed is $$\frac{9}{10}$$. What is the original fraction ?
1). $$\frac{3}{4}$$
2). $$\frac{1}{4}$$
3). $$\frac{3}{5}$$
4). $$\frac{2}{5}$$
Let numerator be x and denominator be y.
If numerator is increased by 200% it becomes 3x and if numerator is increased by 150% it becomes 2.5y
Now the new fraction is 9/10.
Hence, (3x/2.5y)=(9/10) which gives $\frac{x}{y}$=$\frac{3}{4}$
