Question

How many Kg of sugar costing Rs 5.75 per Kg should be mixed with 75 Kg of cheaper sugar costing Rs 4.50 per Kg, so that the mixture is worth Rs 5.50 per Kg?

• A. 250 Kg
• B. 300 Kg
• C. 350 Kg
• D. 325 Kg
• E. None of the above

Answer 1

The correct option is B 300 Kg


Quantity of cheaper sugar: Quantity of superior sugar =0.25 : 1
or, $\frac{Quantityofcheapersugar}{Quantityofsuperiorsuper}=\frac{0.25}{1}=\frac{1}{4}$
$\Rightarrow \frac{75}{Quantityofdearersugar}=\frac{1}{4}$
$\therefore$ Quantity of dearer sugar $=75\times 4=300Kg$
