Solution

Given :-

• Selling price of any item = ₹18,000
• Lose percentage = 10%

Find :-

• Cost price of item

Explanation

Important Formula

★ Cost price = (100 * Selling price )/(100 - lose%)

So, keep all above Value

==> Cost price = 100 * 18,000/(100-10)

==> Cost price = (100 * 18,000)/(90)

==> Cost price = 100 * 200

==> Cost price = ₹ 20,000

Hence

• Cost price of item will be = ₹ 20,000

Answer Verification

Here,

• Cost price = ₹ 20,000
• Selling price = ₹ 18,000

Formula

★ Lose = Cost price - Selling price

So,

==> Lose = 20,000 - 18,000

==> Lose = ₹ 2, 000

Now, Again use formula

★ Lose% = Lose * 100/Cost price

So, Now

==> Lose % = 2,000 * 100 / 20,000

==> Lose % = 20 /2

==> Lose % = 10%

Hence, proved
