Answer» Either A and B and C are sufficient to answer the question Either A and B or A and C are sufficient to answer the question Either A and C or B and C are sufficient to answer the question A, B and C together are sufficient to answer the question Solution :From `ATO` LET selling price of 4 watches `=12x` COST price of 4 watches `=12xxx2/3=8x` Profit EARNED on 4 watches `=12x-8x=4x` Cost price of 3 shirts `=12x` Profit earned on selling 1 watch = x Profit earned on selling 1 shirt `=2x` Profit earned on selling 2 shirts `=4x` Required profit precentage `=(x+4x)/(2x+8x)xx100=50%` From `Bto` Lets elling price of 2 shirts and 6 watches be 12x and 18y respectively. If profit `%` is 50, we can calculate total profit i.e. `1/3(12x+18y)=4x+6y.` This profit is equal to `500%` of CP of 1 watch. But we don't know Cp of a wathc, hence we can't calculate further. From `Cto` Let cost price of watch is 'a' and cost prie of shirt is 'b' Calculate further. Now combining the statement B and C `b+a=6x` `(500)/(100)(a)=5a=4x+6y` We can't solve it further, as we don't solvet it further, as we don't know whether profit or loss earned on selling the wathch. Statement 'A' alone is sufficient to answer the question, but statement 'B'alone is not sufficient to answer the questions.
