1. Ronald sold a smartwatch for $376 at a loss of 6%. Find the cost price of the smartwatch.
a) $400
b) $350
c) $300
d) $250
Answer: a) $400
Explanation: Cost price = Selling price x 100/(100 - loss%)
= $376 × 100/(100-6)
= $376 × 100/94 = $400
2. A boy buys 9 apples for $9.60 and sells them at 11 for $12. Find his gain or loss percent.
a) 2%
b) 2.75%
c) 2.83%
d) 3%
Answer: c) 2.83%
Explanation: CP of 9 apples = $9.60
CP of 1 apple = $9.60/9 = 1.06
SP of 11 apples = $12
SP of 1 apple = 12/11 = 1.09
Clearly,
SP of 1 apple > CP of 1 apple
We get profit on selling apples = SP - CP = 0.03
Gain% = (0.03/1.06) x 100
= 2.83%
3. A dealer buys furniture for $225 and spends $15 on its repairs. If he sells the same for $300, find his profit percentage.
a) 10%
b) 15%
c) 20%
d) 25%
Answer: d) 25%
Explanation: A dealer buys furniture for $225
Money spent on repairing the furniture = $15
Total expenses = $(225 + 15) = $240
Here, we consider total expenses as CP.
CP = $240
SP = $300
Profit = SP – CP = $(300 - 240) = $60
Profit% = (60/240) x 100
= 25%
4. Profit after selling a commodity for $425 is same as loss after selling it for $355. The cost of the commodity is:
a) $385
b) $390
c) $395
d) $400
Answer: b) $390
Explanation: Let CP = $x
Profit on $425 = Loss on $355
SP – CP = CP – SP
425 – x = x – 355
2x= 780
x = $390
5. A merchant marks his goods up by 75% above his cost price. What is the maximum discount% that he can offer so that he ends up selling at no profit or no loss?
a) 42.85%
b) 40.04%
c) 39.82%
d) 33.45%
Answer: a) 42.85%
Explanation: Let us assume that the cost price of the article = $100
Therefore, the merchant would have marked it as $100 + 75% of $100 = 100 + 75 = 175.
Now, if he sells it at no profit or no loss, he sells it at the cost price.
Discount = 175 – 100 = 75
i.e., he offers a discount of $75 on his selling price of $175
Therefore, his discount% = (75/175) x 100 = 42.85%
