Question

A CD player was purchased for ₹ 3,200 and ₹ 560 were spent on its repairs. It was then sold at a gain of 12 %. How much did the seller receive? ​

Answer 1

Answer:

₹ 4211.2

Step-by-step explanation:

Total money spent on the CD player (CP) = ₹3200 + 560

                                                                     = ₹3760

Let the selling price or SP be x

Total gain on the player = ₹ ( 3760 × 12/100 )

                                        = ₹ 451.2

∴ X = ₹ (3760 + 451.2)

     = ₹ 4211.2

Answer 2

✬ S.P = 4211.2 ✬

Step-by-step explanation:

Given:

• Cost price of CD player is Rs 3200.
• Amount spent of repairing is Rs 560.
• Seller gained 12 % on selling.

To Find:

• What is the S.P of CD ?

Solution: Let the selling price be Rs x.

➟ Total CP = 3200 + amount spent on repairing

➟ 3200 + 560 = Rs 3760

Here we have

• CP = Rs 3760
• Gain % = 12%

To find selling price when CP and gain % are given we use the following formula

★ S.P = (100 + gain %/100) × C.P ★

$\implies{\rm }$ x = (100 + 12/100) × 3760

$\implies{\rm }$ 112/100 × 3760

$\implies{\rm }$ 112/10 × 376

$\implies{\rm }$ 42112/10

$\implies{\rm }$ 4211.2

Hence, seller received Rs 4211.2 after selling CD player at 10% gain.

• Other Formulae
• S.P = 100 – loss%/100 × C.P
• C.P = 100/100 – loss % × S.P
• C.P = 100/100 + gain % × S.P
