If the numerator of a fraction is increased by 250% and the denominator is increased by 400%. The resultant fraction is $$\frac{7}{19}$$. What is the original fraction ?
1). $$\frac{10}{19}$$
2). $$\frac{5}{9}$$
3). $$\frac{9}{5}$$
4). $$\frac{19}{5}$$
Let the two numbers be a,b
We have the new fraction as (a+2.5a)/b+4b=7/19;
35a/50b=7/19;
After simplification we get 10:19 As the answer.
