1Rs. 3000
2Rs. 3500
3Rs. 4000
4Rs. 2500

Answer:- 1

Explanation:-

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}

$\eqalign{ & \therefore 357:\left( {49 \times 12} \right)::1517.25:x \cr & \Leftrightarrow 357x = \left( {49 \times 12 \times 1517.25} \right) \cr & \Leftrightarrow x = \frac{{\left( {49 \times 12 \times 1517.25} \right)}}{{357}} \cr & \Leftrightarrow x = 2499 \cr}$
Hence, the approximate price is Rs. 2500
