The Brainliest Answer!

Selling price of the calculator at 18% gain={(100+gain%)/100 x CP}

=Rs.{(100+18)/100 x X}=Rs.(118X/100)

Selling price of the calculator at 20% gain={(100+gain%)/100 x CP}

=Rs.{(100+20)/100 x X}=Rs.(120X/100)

According to the question,

120X/100-118X/100=16

2X/100=16

X=16 x 100/2

X=rs.800
