Question

I bought
5%. Gest Find the price of pens
before GST


​

Answer 1

Question :-

• A product was bought including GST 5%. Find the price before GST was added.

To find :-

• The price before GST was added.

Since the Selling price is not given, we can assume the selling price to be ₹105.

Let Cost price be ₹x

Formula to use :-

As we know that when GST is added, then the Selling price is greater than the Cost price, we can use the formula :-

$Selling \:\:Price = \dfrac{100+Profit\%}{100} \times Cost \:\:Price$

Taking the GST %  as Profit %.

Substituting the values,

$105 = \dfrac{100+5}{100} \times x$

$105 = \dfrac{105}{100} \times x$

By transposing 100 to the LHS (Left hand side),

$105\times100 = 105 \times x$

Transposing 105 to the LHS(Left hand side),

$\dfrac{105\times100}{105} = x$

By reducing to the lowest terms,

₹100 = x

Hence,

CP = ₹100

Hope it helps!

Happy day!
