Question

A man sells one speaker for * 7,500 at a profit of 20% and another speaker for
* 8,100 at a loss of 10%. Find his total loss or profit.
(1)Loss = 300
(2)Loss = * 350
(3)Profit = * 300
(4) Profit = 350​

Answer 1

Answer:

5.24%

Step-by-step explanation:

Given that,

profit the man earn is 20% on a camera which he sells for = 7500

loss the man had is 5% on another camera which he sells for = 8550

To find,

total loss or gain%

First we will calculate cost price

PROFIT:

7500 = originalPrice + 20% of originalPrice

7500 = x + (20/100)*x

7500 = x + 0.2x

7500 = 1.2x

x = 7500/1.2

x = 6250

LOSS:

8550 = originalPrice - 5% of originalPrice

8550 = x - (5/100)x

8550 = x - 0.05x

8550 = 0.95x

x = 9000

Total C.P. = 6250 + 9000 = Rs. 15250

Total S.P. = 7500 + 8550 = Rs. 16050

Selling Price > Cost Price, hence man gains during this transaction.

Gain = S.P. – C.P. = 16050 – 15250 = Rs. 800

Gain% = (800× 100) / 15250 = 5.24%

Answer 2

Answer:

profit =350

Step-by-step explanation:

first speaker cp =

$7500 \times (\frac{100}{100 + 20}) \\ = 7500 \times \frac{100}{120} \\ = 6250$

profit = 7500-6250=1250

on 2nd speaker cp =

$8100 \times ( \frac{100}{100 - 10} ) \\ = 8100 \times \frac{100}{90} \\ = 9000$

loss =9000-8100=900

so profit = 1250-900=350
