Question

A man sells one camera a for rs. 7500 at a gain of 20% and another camera b for rs. 8550 at a loss of 5 %. Find his total loss or gain%.

Answer 1

Answer:

gain% = 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%
