• A. ₹3529.50
• B. ₹3500
• C. ₹3592.50
• D. ₹3259.50

Answer 1

The correct option is C ₹3592.50

Given,
2 dollars is equal to ₹143.70

More the dollars, more the value in rupees.

$\text{So, Dollars}\left(x\right)\propto \text{Indian Rupees(y)}$
$\therefore \frac{x_1}{y_1}$ = $\frac{x_2}{y_2}$

Given,
$x_1=2$
$y_1=₹143.70$
$x_2=5$
$\text{and}{y}_2=?$

$\Rightarrow y_2=\frac{x_2\times y_1}{x_1}$

$\Rightarrow y_2=\frac{50\times 143.70}{2}=3592.50$

Hence 50 dollars is equal to ₹3592.50
