In each of the following questions is followed by information given in three statements. You have to study the questions along with the statements and decide the information given in which of the statement(s) is necessary and sufficient to answer the question.
Clearly each statement alone is not sufficient.
I & II : Let CP = 100x
=> SP = 120x [Since, profit = 20%]
Profit = 120x - 100x = 20x = 1200 => x = 60
SP = 7200
Thus, I & II are sufficient.
I & III : CP = 15000
Profit% = 20%
=> SP = 18000
Thus, I & III are sufficient.
II & III : CP = 15000
Profit = 1200
=> SP = 15000+1200 = 16200
Thus, II & III are sufficient.
Therefore, any two of the three statements is sufficient.
