Question

How many kilograms of Basmati rice costing Rs.33/kg should a shopkeeper mix with 30 kg of ordinary rice costing Rs.24 per kg so that he makes a profit of 25% on selling the mixture at Rs.35/kg?

• A. 20 Kg
• B. 24 Kg
• C. 30 Kg
• D. 25 Kg

Answer 1

The correct option is B 24 Kg

If he wants to earn 25% profit by selling it at 35 Rs./Kg, then the cost price should be $\frac{35}{5}\times 4=28$ Rs./Kg
The required ratio is 4:5.
Now, 5x = 30 $\Rightarrow 4x=24$
Basmati rice required is 24 Kg.
