Question

a product blend two qualities of rice one costing rupees 12. 50 per kg and the other costing rupees 14 per kg in the ratio of 4 is to 5 find its profit percent if he sells the mixture @ rupees 16 per kg

Answer 1

The profit percent is 120% (Or the increase is 20% depending on how your answer must be formatted)

Begin by multiplying the ratio by the price values. 12.50(4) + 14.00(5)

This gives 50+70, which is rupees 120 /9 kg

Next, you divide by the 9 kg, so that you can find the price per kg

This gives you a rate of rupees $13\frac{1}{3}$ per kg.

Next, you must divide the price that it is being sold at for the price that it cost. This will be $\frac{16}{13\frac{1}{3}}$

This simplifies to $\frac{1.20}{1}$

Next you convert this to a percentage by moving the decimal 2 places to the right. This gives you a 120% profit percent
