Calculation:
Option:1
1 dozen = 12 items
⇒ 16 dozen = 16 × 12 = 192 items
Cost of each item = Rs.18.50
⇒ Cost of 192 items = 18.50 × 192 = Rs.3,552
Option: 2
Cost of 1 packet = Rs. 21.50
⇒ Cost of 170 packets = 21.50 × 170 = Rs.3,655
Option:3
1 dozen = 12 items
⇒ 12 dozen = 12 × 12 = 144 items
Cost of each item = Rs. 25
⇒ Cost of 144 items = 25 × 144 = Rs. 3,600
Option:4
Cost of 1 packet = Rs.16.50
⇒ Cost of 220 packets = 16.50 × 220 = Rs. 3,630
