Question

John buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, what is his gain percent ?

a)
12%
b)
10%
c)
4 + 4 / 7%
d)
5 + 5 / 11%

Correct answer is option 'D'. Can you explain this answer?

Answer

4700 +800= 5500 is the total amount he invest in the old scooter.
s.p.= 5800-5500 = 300
300 is the 5.5% of the 5500
so his gain profit is 5.5%
answer D..

Answer

Yes see... CP was 4700 and then he spent 800 on repairing so final CP= 4700+800=5500
SP= 5800
that means profit= 5800-5500= Rs300

Now, Gain%= Gain*100/CP
ie. Gain%=300*100/5500= 66/11 ans.

Answer

Given:
Cost price (CP) = Rs. 4700 + Rs. 800 = Rs. 5500
Selling price (SP) = Rs. 5800

To find:
Gain percent

Solution:
Formula for calculating gain percent is:

Gain percent = (Profit / CP) x 100

where,
Profit = SP - CP

Substituting the given values, we get:

Profit = SP - CP = Rs. 5800 - Rs. 5500 = Rs. 300

Gain percent = (Profit / CP) x 100 = (300 / 5500) x 100 = 5 5/11%

Therefore, the gain percent is 5 5/11%, which is option (d).

Answer

300/5500
