Question

A shopkeeper buys rice for Rs.50 per kg and wheat for Rs. 40 per kg for every 3kg of rice he buys 4kg of wheat he sells them for profit of 8% for rice and 10% for wheat his total sale is rs. 33800 how much rice did he buy

Answer 1

Given:-

• Selling price of wheat = 110/100 × 40 = 44

• Selling price for rice = 108/100 × 50 = 54

• The ratio of the amounts of rice to wheat is : Rice : Wheat = 3 : 4

Solution:-

Let x be the total amount of rice and wheat.

$\sf \: The \: amount \: of \: rice = \dfrac{3}{7}x$

$\sf \: Wheat = \dfrac{4}{7}x$

${ \bigstar{ \underline{According \: to \: the \: question,}}}$

$\sf \: Total \: no. \: of \: sales :-$

$\sf \implies \: ( \frac{3}{7}x \times 54) + ( \frac{4}{7}x \times 44) = \frac{338}{7}x \\ \sf \implies \: \frac{338}{7}x = 33800 \\\sf \implies \: x = 33800 \times \frac{7}{338} \\\sf \implies \: x = 700$

$\sf \: Amount \: of \: rice :-$

$\sf \implies \: \dfrac{3}{7} \times700 \\ \sf \implies \:300$

$\therefore$Shopkeeper bought 300kg rice.
