Option 2: Rs. 1,000
Option 3: Rs. 500
Option 4: Rs. 2,400
Correct Answer: Rs. 500
Solution : Given that the ratio of the prices of A and B is 5 : 9, and the prices of C and D are 24 : 13. Let the prices of A, B, C, and D be $5x$, $9x$, $24y$, and $13y$ respectively. So, $13y=1300$
Question : If the numerator of a fraction is increased by 140% and the denominator of the fraction is decreased by 20%, the resultant fraction is $\frac{12}{7}$. Find the original fraction.
Option 1: $\frac{4}{9}$
Option 2: $\frac{4}{7}$
Option 3: $\frac{7}{6}$
Option 4: $\frac{8}{9}$
Correct Answer: $\frac{4}{7}$
Solution : Let $\frac{x}{y}$ be the original fraction. The fraction's numerator is increased by 140% and the denominator is decreased by 20%. $\frac{x+1.4x}{y-0.2y} = \frac{12}{7}$ ⇒$\frac{2.4x}{0.8y} = \frac{12}{7}$ ⇒$\frac{3x}{y} = \frac{12}{7}$ ⇒$\frac{x}{y} = \frac{12}{7\times 3}$ ⇒$\frac{x}{y} = \frac{4}{7}$ Hence, the correct answer is $\frac{4}{7}$.
