wrong question (Question:633245.0)

profit becomes thrice and not the percent profit

Question:
The per cent profit made when an article is sold for Rs 56 is thrice as when it is sold for Rs 42. The cost price of the article is:
Options:
A) Rs 48
B) Rs 49
C) Rs 50
D) Rs 35
Solution:
Ans: (d)  

Profit = income - cost

the equation:

3p = 56 - c --- (i)

P = 42 - C ---- (ii)

After solving the equation (i) and (ii)

P = 7

The option for P = 42 - C we get,

7 = 42-C

C= 35 Rs.
