Answer 1

Answer:

Step-by-step explanation:Cost of

180 pencils(15 packets with 12pencils each) =288

Cost of 1 pencil= 288/180=1.6

Cost of 20 packets of 10 pencils = 200 * 1.6=320

Answer 2

Cost would be Rs. 320.

Step-by-step explanation:

Since we have given that

15 packet of 12 pencil = Rs. 288

So, Total number of pencils would be

$15\times 12=180$

So, Number of each pencil would be

$\dfrac{288}{180}=1.6$

So, if the number of packets = 20

Number of pencils = 10

So, Total number of pencils  = $10\times 20=200$

So, Total cost would be $200\times 1.6=320$

Hence, Cost would be Rs. 320.
