Number of packets of biscuits packed in 7 minutes = 280 biscuits

Step-by-step explanation:

Given

• A machine can pack 120 packets of biscuit in 3 minutes.

To Find

• Number of biscuits pack in 7 minutes.

Solution

A machine can pack 120 packets of biscuit in 3 minutes.

120 packets of biscuits = 3 min

First we have to find how many biscuits are packed in 1 min. For this we must divide 120 packets/3 minutes

• 》120/3 = 40 packets of biscuits

So, 40 packet of biscuits are packed in 1 minute.

So,

∴ Number of packets of biscuits packed in 7 minutes = 7 × number of biscuits packed in 1 minutes

• 》7 × 40

• 》280

So,∴Number of packets of biscuits packed in 7 minutes = 280 biscuits
