Solution

The correct option is A 1188

Let CP of the table-fan be ₹x.

If SP = ₹891 , Loss % = 10%

CP - Loss = SP

x10x100 = ₹891

100x10x100 = ₹891

90x100 = ₹891

x = 891×10090 = ₹990

To make a profit of 20%,

SP = CP + Profit

SP=990+20100×990
SP=990×(1+20100)
SP=990×(1+0.2)
SP=990×(1.2)
SP = 990 × 1.2 = ₹1188
