Answer 2

✬ Selling Price = Rs 96 ✬

Step-by-step explanation:

Given:

• Marked price of dress is Rs 120.
• Discount percent is 20%.

To Find:

• What is selling price of dress ?

Solution: Here we have given M.P and Discount %.

To find S.P when M.P and Discount % are given we use the formula.

★ S.P = M.P(100 – Discount%/100) ★

$\implies{\rm }$ S.P = 120(100 – 20/100)

$\implies{\rm }$ S.P = 120(80/100)

$\implies{\rm }$ S.P = 9600/100

$\implies{\rm }$ S.P = 96

Hence, selling price of dress is Rs 96.

Another Method: Here we have 20% discount on 120.

∴ Total discount = 20% of 120

➫ Discount = 20/100(120)

➫ 120/5 = Rs 24

As we know that

★ Discount = M.P – S.P ★

$\implies{\rm }$ 24 = 120 – S.P

$\implies{\rm }$ 24 – 120 = – S.P

$\implies{\rm }$ – 96 = – S.P

$\implies{\rm }$ 96 = S.P

Hence, S.P is Rs 96.
