1. The price of 357 mangoes is Rs. 1517.25. What will be the approximate price of 49 dozens of such mangoes ?

A. Rs. 3000

B. Rs. 3500

C. Rs. 4000

D. Rs. 2500

Solution:

Let the required price be Rs. x
More mangoes, More price (Direct proportion)

\begin{aligned} ∴ 357 : (49 \times 12) :: 1517.25 : x \\ \Leftrightarrow 357 x = (49 \times 12 \times 1517.25) \\ \Leftrightarrow x = \frac{(49 \times 12 \times 1517.25)}{357} \\ \Leftrightarrow x = 2499 \end{aligned}

Hence, the approximate price is Rs. 2500
