Resham purchased a packet of 18 pens for Rs 56 and another packet of 8 pens for Rs 45 . Which packet was costlier and why??

The second packet.

Step-by-step explanation:

First Packet:

Cost of 18 pens = Rs 56

Cost of 1 pen = Rs 56 ÷ 18 = Rs 3.11 (rounded off to 2 decimal places)

Second Packet:

Cost of 8 pens = Rs 45

Cost of 1 pen = Rs 45 ÷ 8 = Rs 5.63 (rounded off to 2 decimal places)

Thus, the second packet is costlier because the cost of 1 pen in the second packet (Rs 5.63) is more than the cost of 1 pen in the first packet. (Rs 3.11)

The packet with 8 pens for Rs 45 is costlier.

Step-by-step explanation:

The unit rate of the first packet is 56 to 18, which can be simplified to the unit rate of $3.11 per single pen. Using the same process, the unit rate of the second packet is $5.63 per single pen.
