​

Answer 1

Answer:

She should sell it at Rs 2070 to make a profit of 15 percent.

Step-by-step explanation:

Given:

Selling price of bicycle = Rs 1638

Loss = 9%

Formula to find cost price when selling price and loss percent is given:

Cost price = (Selling price × 100)/(100 - loss%)

Cost price = Rs (1638 × 100)/(100 - 9)

Cost price = Rs 163800/91

Cost price = Rs 1800

Now, Formula to find selling price to make a profit of 15%:

Selling price = Cost price(100 + profit%) / 100

Selling price = Rs 1800(100 + 15)/100

Selling price = Rs 18 × 115

Selling price = Rs 2070

Answer 2

Answer:

Given :-

• By selling a bicycle for Rs 1638, Ishita loses 9%.

To Find :-

• What is the price she sell it to make a profit of 15%.

Formula Used :-

➤ To find Cost Price or CP we know that,

★ CP = 100(100 - Loss%) × SP ★

➤ To find Selling Price or SP we know that,

✯ SP = (100 + Profit%)/100 × CP ✯

Solution :-

➦ First, we have to find the Cost Price or CP,

Given :

• Selling price = Rs 1638
• Loss% = 9%

According to the question by using the formula we get,

⇒ CP = 100/(100 - 9) × 1638

⇒ CP = 100/(91) × 1638

⇒ CP = 100/91 × 1638

⇒ CP = 100 × 18

➠ CP = Rs 1800

Hence, the cost price is Rs 1800

➦ Now, we have to find the selling price or SP,

Given :

• Profit = 15%
• Cost Price = Rs 1800

According to the question by using the formula we get,

↦ SP = (100 + 15)/100 × 1800

↦ SP = (115)/100 × 1800

↦ SP = 115/100 × 1800

↦ SP = 115 × 18

➠ SP = Rs 2070

∴ The price she sell it to make a profit of 15% is Rs 2070 .
