Answer 1

Here we have been asked to find the cost of 1 shirt if the cost of 21 shirts is 8064 Rs.

There are two methods for solving the given problem :

1. Unitary method
2. Cross multiplication

➜ Unitary method :

Here we find the value of 1 thing and then multiply with other content .

Here the other content is given and asked for 1 thing. We simply need to divide 8064 with 21.

☞$\sf{\dfrac{8064}{21}}$

☞$\sf{\cancel{\dfrac{8064}{21}} \implies 384}$

So the cost of 1 shirt is 384 Rs.

➜ Cross Multiplication :

Here we simply take the numbers side by side and cross multiplication will be done.

☞$\sf{21 = 8064}$

☞$\sf{1 = ?}$

☞$\sf{\dfrac{8064 \times 1}{21}}$

☞$\sf{\cancel{\dfrac{8064}{21}} \implies 384}$

So the cost of 1 shirt is 384 Rs.

Using Unitary method,

Cost of 21 shirts = Rs. 8064

Cost of 1 shirt = 8064/21

= Rs. 384

Thus, answer = Cost of 1 shirt is 384.

Explanation :-
