Answer 1

Given : Cost price = 7640, Gain = 15%.

We know that selling price = Cost price * [(100 + Gain%)/100]

⇒ 7640 * [(100 + 15)/100]

⇒ 7640 * [(115)/100]

⇒ 7640 * 1.15

⇒ 8786.

(iii) Given Cost price = 720, Loss = 8 3/4%.

We know that Selling price = [(100 - Loss%)/100] * CP

⇒ [(100 - 35)/400] * 720

⇒ 0.1625 * 720

⇒ 117.

Hope this helps!

Answer 2

$\huge{\mathfrak{\pink{\underline {Solution }}}}$

1) Given,

CP = Rs 7640

Gain = 15%

SP = ?

We know that

$\bold\pink{SP = \frac{(100 + gain\%)}{100} \times CP }\\ \\ \: \: \: \: \: \: \bold\pink{= Rs[ \: \: \frac{(100 + 15)}{100} \times 7640]} \\ \\ \: \: \: \: \: \: \bold\pink{= Rs \: \: (\frac{115}{100} \times 7640)}$

$\: \: \: \: \: \:\bold \pink{= Rs \: \: 8786}$

2) Given,

CP = Rs 720

$\bold{loss = 8 \frac{3}{4} \%} \\ \\ \: \: \: \: \: \: \: \: \: \bold{= \frac{35}{4} \%}$

SP = ?

We know that

$\bold\pink{SP = \frac{(100 - loss\%)}{100} \times CP} \\ \\ \: \: \: \: \: \: \bold\pink{= Rs \: \: [\frac{(100 - \frac{35}{4}) }{100} \times 720]} \\ \\ \: \: \: \: \: \: \bold\pink{= Rs \: \: [\frac{(400 - 35)}{100 \times 4} \times 720]}\\ \\ \: \: \: \: \: \: \bold\pink{= Rs \: \: (\frac{365}{400} \times 720)} \\ \\ \: \: \: \: \: \: \bold\pink{= Rs \: \: 657}$
