Ann's new bicycle

by pareekbharat86 » Sun Dec 15, 2013 3:59 am
Ann can have her bicycle repaired for $50, or she can trade it in, as is, and receive $22 credit toward the purchase of a new bicycle that sells for $107. If Ann trades in her current bicycle, the cost to her of purchasing the new bicycle is what percent greater than the cost of having her current bicycle repaired?
(A) 44%
(B) 60%
(C) 70%
(D) 114%
(E) 170%

OA is C.

I also checked C. But isn't the true 'cost' 107 instead of 85? She is giving up her old bicycle which probably costs 22$ in the market today. From a finance point of view, the true cost to Ann must be 107 and the answer should be [spoiler]114% i.e. D[/spoiler]

Correct me if I am wrong.
Thanks,
Bharat.

I don't know enough about accounting/finance to say whether or not the "true cost" is $107 or $85.

However, if the correct answer is C, then I suppose they are referring to the net cost of the new bike (although I don't know enough about accounting/finance to say whether or not the term "net cost" is accurate here either :-))

Here's a hypothetical question: let's say a new bike costs only $50, which means Ann can just trade her old bike for a new bike.
Would you say that the new bike cost $50 or $0

Cheers,
Brent

Cost to repair old bike: $50
Net cost of new bike = $107 - $22 = $85

The cost of purchasing the new bicycle is what percent greater than the cost of having her current bicycle repaired?

In other words, $85 is what percent greater than $50?
Well, $85 is what $35 greater than $50
So, 35/50 = 70/100 = [spoiler]70% = C[/spoiler]

The quoted part means -

Cost of repairing the cycle is $50

Cost of New Cycle is $ 107

Selling Price of Old Bicycle is $ 22

Since the new cycle is being sold at $ 107 and she receives $22 for that it means that whe will have to pay just $85 for the new bicycle..

Selling Price of Old Bicycle is $ 22

Cost of New Bicycle is $ 85

Cost of having her current bicycle repaired is $ 50

Amount which Ann has to pay more is $ 35


So the required % is (35/50 )*100 => 70%
