Detailed Solution

Concept: First find the price at which the coffee is sold by each shopkeeper and then compare the prices.
The cost of one packet of coffee is Rs240.
The cost of reduction by the first shopkeeper is,

240 \times 1 / 5 = 48

240 - 48 = Rs 192

The cost of reduction by the second shopkeeper is,

240 \times 1 / 10 = 24

240 - 24 = Rs 216

As the amount of the first shopkeeper is less than the second shopkeeper, so, the offer of the first shopkeeper is better.
The difference in the two offers is 216-192, or Rs. 24.
Consequently, Rs 24 is the price at which the coffee is sold.
Hence, the correct option is 1.[12]
