1.  Alfred buys an old scooter for ₹ 4700 and spends ₹ 800 on its repairs. If he sells the scooter for ₹ 5800, his gain percent is:
A. 4(4/7)%
B. 5(5/11)%
C. 10%
D. 12%

Answer: Option B

Explanation:

Cost Price (C.P.) = ₹ (4700 + 800) = ₹ 5500.

Selling Price (S.P.) = ₹ 5800.

Gain = (S.P.) - (C.P.) = ₹ (5800 - 5500) = ₹ 300.

Gain % = 300 x 100 % = 5 5 %
5500 11
