Then 1920 biscuit need for packet
1920/384= 5
5 carton required.

Answer 2

Dear friend,

No. of packets = 288
No. of biscuits 1 packet contains = 12 biscuits
Total no. of biscuits = 3456
No. of cartons = 9

Then,
Cartons for 3456 biscuits = 9
Cartons for 1 biscuit = 9/3456
Cartons for 1920 biscuits = (9/3456) × 1920
= 5

Answer. 5 cartons are needed.

Hope it helps !!!
