Question

please give the explanation for this questions​

Answer 1

Step-by-step explanation:

1) MP = ₹900

Discount% = 25%

Then, the remain cost = 100% - 25% = 75%

Hence,

SP = MP × (Remaining cost)%

SP = ₹900 × 75%

$900 \times \frac{75}{100}$

$9 \times 75$

$9 \times 75 = 675$

Hence,

SP = ₹675

If he still gains 12.5%

100% - (gain%)

100% - 12.5% = 87.5%

Hence,

CP = SP × 87.5%

CP = ₹590.625

2)MP = ₹1000

Discount = 20%

Then, the remain cost = 100% - 20% = 80%

SP = MP × (Remaining cost)%

$1000rs. \times 80\%$

$1000 \times \frac{80}{100}$

$10 \times 80$

$800$

Hence, SP = ₹800

3)MP = ₹5,000

SP = ₹4,000

Discount = MP - SP

Discount = ₹5,000 - ₹4,000

Discount = ₹1,000

$discount\% \: = \: \frac{discount}{mp} \times 100$

Discount% = ₹1000/₹5000 × 100

Discount% = 1/5 × 100

Discount% = 20%

Hence,

Discount% = 20%
