Question

How should we mix two rice packets to get one $1kg$ packet priced at $Rs8$ when the prices of $1kg$ packets of the two types are $Rs7.1$ and $Rs9.2$.

• A. $4:3$
• B. $3:4$
• C. $4:5$
• D. $5:4$

Answer 1

Answer: (A)

$4:3$

The cost of two types of packet are Rs. 7.1 and Rs 9.2

We need to mix two rice packet at Rs 8

The difference in the price and first packet cost=8-7.1=Rs. 0.9

The difference in the price and second packet cost=9.2-8=Rs. 1.2

We need to mix them in the ratio $1.2:0.9=4:3$
