Answer:
Rs. 324
Explanation:
Find cost of one pencil of the first one. Then use that to find total cost of the other question.
Cost of one pencil = ?
No. of packets = 25
No. of pencils in one packet = 12
Total money = Rs. 360
No. of pencils = 25 × 12 = 300
Cost of one pencil = Total money ÷ No. of pencils
= 360 ÷ 300 = Rs. 1.2
Cost of 27 packets of 10 pencils each = ?
No. of packets = 27
No. of pencils in one packet = 10
Cost of one pencil = 1.2 Rs.
No. of pencils = 27 × 10 = 270
Total cost of pencils = Cost of one pencil × No. of pencils
= 1.2 × 270 = Rs. 324
Therefore, cost of 27 packets of 10 pencils each is Rs, 324
