Question

One packet containing 5 pencils is available for Rs. 13. Another packet
containing 10 pencils is available for Rs. 25. Which packet has a lesser rate
per pencil?​

Answer 1

Step-by-step explanation:

Given total cost of 5 pens and 10 pencil = Rs 30

5 pens + 10 pencils = 30

pens + 2 pencils = 1

also given pen cost 3 more than a pencil

i.e, pen = 3 + pencil.

pen - pencil = 3

pens + 2 pencils = 6

_______________

-3 pencils = -3

pencils = 1

pen - 1 = 3

pen = 4

cost of pencils = 1 cost of pen = 4

Answer 2

Answer:

Second packet

Step-by-step explanation:

Cost of 5 pencils in first packet = ₹13

Cost of 1 pencil in first packet  = 13/5 = ₹2.6

Cost of 10 pencils in second packet = ₹25

Cost of 1 pencil in second packet = 25/10 = ₹2.5

₹2.5<₹2.6
