Answer» Cost price is ₹ 300 and Loss per day would be ₹ 8,100 .Step-by-step EXPLANATION:LET the cost price of a wristwatch = xLoss on each watch = 18%Selling price of the wristwatch = \frac{x(100-18)}{100} 100x(100−18) = \frac{82x}{100} 10082x ---------(1)Gain would have been = 5%When selling price would have been = \frac{x(100+5)}{100} 100x(100+5) = \frac{105x}{100} 100105x ---------(2)Now subtract equation (1) from equation (2)\frac{105x}{100}-\frac{82x}{100}=69 100105x − 10082x =69\frac{23x}{100}=69 10023x =69x = \frac{69\times 100}{23} 2369×100 x = 300 Rs.Loss = 18% × 300 = 0.18 × 300 = 54 Rs.Selling price = 300 - 54 = 246Since loss on one wrist watch = 54 Rs.Loss on 150 watch = 54 × 150 = 8,100 Rs.Cost price is ₹ 300 and Loss per day would be ₹ 8,100 .mark as btainlist
