(1) the money I have before buying the shirt.
(2) the cost of the shirt

please answer step by step​

Answer 1

Answer:

1.) The total money is Rs. 1350.

2.) The cost of the shirt is Rs. 810.

Step-by-step explanation:

1.) The money left is 2/5 th of the total money.

So, money spent on the shirt = Total - 2/5

=> 1 - 2/5 => 5/5 - 2/5 => 3/5 th of money was spent on shirt.

Now, the money left is Rs. 540 and it is given that Rs. 540 is 2/5 th of the total money.

Let total money be x.

So, (2/5)x = 540

∴ x = 540 ÷ 2/5    (Signs change to their inverse while switching sides in an equation)

=> 540(5/2)    (Dividing by a number is the same as multiplying by its reciprocal)

=> (540/2)*5 => 270*5 => Rs. 1350 is total money.

2.) As the money left is Rs. 540 and the total money is Rs. 1350, the cost of the shirt = 1350 - 540 => Rs. 810.
