Question

if Ahmed sells his old mobile phone for rupees 5000 he would lose 25% at what price must he sell his mobile phone to gain 15%​

Answer 1

Answer:

He has to sell his mobile phone for ₹ 7666.66.

Step-by-step explanation:

SP - ₹ 5000

Loss % - 25%

CP = 100 / ( 100 - loss % ) * SP

CP = 100 / ( 100 - 25 ) * 5000

CP = 100 / 75 * 5000

CP = 500000 / 75

CP = ₹ 20000 / 3

According to the question : -

Gain% - 15 %

SP = ( 100 + GAIN % ) / 100 * CP

SP = ( 100 + 15 ) / 100 * 20000 / 3

SP = 115/100 * 20000 / 3

SP = ₹ 7666.66...

★GIVEN★

• Selling price of old phone=₹5000
• loss on phone=25%

★FIND: NEW SELLING PRICE OF PHONE

• ACCORDING TO QUESTION★

✼Selling price=5000

✼loss=25%

✼Cost price of phone

$↪cp = \frac{100}{100 - l} \times sp \\ \\↪cp = \frac{100}{100 - 25} \times 5000 \\ \\ </p><p>↪cp = \frac{100}{75} \times 5000 \\ \\ ↪cp = \frac{20000}{3}$

NOW , WE HAVE TO CALCULATE THE NEW SELLING PRICE

• Cost price=20000/3
• profit=15%

❀The new selling price of phone❀

$↪sp = \frac{100 + p\%}{100} \times cp \\ \\ ↪sp = \frac{100 + 15}{100} \times \frac{20000}{3} \\ \\ ↪sp = \frac{115}{100} \times \frac{20000}{3} \\ \\ ↪sp = \frac{23000}{3} = 7666.66$

HENCE:-
