Dear Student, CP of Coat = x then CP of Shirt = 7x/12 SP of Coat= x+y and SP of Shirt= 7x/12+ y where y is the amount of profit Then ATQ, 19x/12 + 2y = 4000 Since, here two variables and one equation so you can find the value x only HIT and Trial Method. HERE.....................CHOOSE ONLY THT OPTION WHICH GIVES LESS THAN 4000 FIGURE WHICH IS SP. SO IF 1120 OPTION HAS GIVEN THEN................. 58.33 = 58 1/3 = 175/3 1120*300/175 = 1920 CP = 1920+1120 = 3040 SP = 4000 SO 4000>3040 OTHER OPTION WILL NOT SATISFIED SUCH A CONDITION......THT'S IT Keep Learning with Us Best Wishes Team Toprankers
