Question

There are 54 rusks in a packet. Usha buys 6 packets. How many rusks does she have?

Answer 1

Hint: We know the number of rusks in a packet. To find the number of rusks Usha has we need to multiply the number of rusks in a packet with the number of packets Usha buys.

Complete step-by-step answer:
We are given that a packet has 54 rusks and Usha buys 6 packets. So, the number rusks Usha have will be equal to the number of rusks in 6 packets.
We know that number of rusks in 1 packet \[ = {\text{ }}54\]
So, the number of rusks in 6 packets is six times the number of rusks in 1 packet.
Number of rusks in 6 packets is $6 \times 54 = 324$
Therefore, the number of rusks that Usha have is 324.

Note: The concept of simple whole number multiplication is used to solve the problem.
Alternate approach to the problem is given by:
Let us consider x be the number of rusks in 6 packets. We know that 54 is the number of rusks in 1 pack.
Now we can take proportions
$ \Rightarrow \dfrac{x}{6} = \dfrac{{54}}{1}$
On multiplying both sides with 6, we get,
$x = \dfrac{{54 \times 6}}{1}$
$ \Rightarrow x = 324$
Therefore, the number of rusks in 6 packs is 324. As Usha has 6 packets of rusks, she will have 324 rusks.
