there in 225 such packets ?​

Answer 1

Given :

• → Number of ball pen packed in 836 packet = 140448.

Need To Find :

• → How many ball-point pens are there in 225 such packets ?

Formula To be Used :

• → Pen in 1 Packet = Total pen / Total Packet

Understanding the concept :

For solving this question we have to first calculate the number of pen In one Packet. There after when we calculate the number of pen in one packet , we can easily calculate number of pen in 225 packet !

According to Question :

• → Pen in 1 Packet = Total pen / Total Packet
• → Pen in 1 Packet = 140448 / 836
• → Pen in 1 Packet = 168 Pens

Pens in 225 Packets :

• → 225 × 168 Pens
• → 37,800 Pens

Therefore :

ᎪNᏚᏔᎬᎡ

✬ Pens = 37800 ✬

Step-by-step explanation:

Given:

Number of ball point pens packed in 836 packets is 140448.

To Find:

How many such pens are there in 225 packets ?

━━━━━━━━━━━━━━━━━━━━━

Solution: Let the number of pens in 225 packets be x.

First of all we have to find that , How many ball point pens are packed in 1 packet ?

We can find it by dividing total number of ball point pens by total number of packets.

➟ Pens in 1 packet = Total pens/Total packets

➟ Pens in 1 packet = 140448/836

➟ Pens in 1 packet = 168 pens

So , We got the number of pens that can be packed in 1 packet.

Now to get the number of total pens that can be packed in 225 such packets , we need to multiply.

➙ Pens in 225 packets :-

Pen in 1 packet × Number of packets

➙ x = 168 × 225

➙ x = 37,800

Hence, 37800 ball point pens are there in 225 such packets.
