Question

A Shopkeeper sells ball pens for Rs 15 each or a packet of 10 for Rs. 120. how much will it cost anisha, if she buys 22ball pens? ​

Answer 1

Answer:

Anisha will pay Rs.270 for 22 pens

Step-by-step explanation:

We are assuming that pens are sold in packets of 10 or in single units.

Hence,

22 pens = 2 packets of 10 each + 2 single units

Cost of 22 pens = 2*(Cost of packet of 10) + 2*(Cost of 1 pen)

Cost of packet of 10 = Rs.120

Cost of single pen = Rs.15

Thus,

Cost of 22 pens = 2*120 + 2*15

                           = 240 + 30

                           = 270

Cost of 22 pens for Anisha = Rs.270

Answer 2

Answer:

120+120+30 = 270

Step-by-step explanation:

Hey, given 1 pen cost =15

A packet of 10 pen cost= 120

if she buys 22 pens then what will be the cost = 10 pen + 10 pen +2 pens = 120+120+30= 270
