Answer 1

selling price of a radio 750 Krishna last 100 so the cost price of Radium is equal to 850
$\frac{12}{100} \times 850 = 102$
so the price must he sell the radio set to gain 12% is equal to 850 + 102 =952

Answer 2

SP =750

CP = (SP +Loss) / (SP - Profit)

CP= 750 +100

CP= 850

New SP

=850 +( 850 ×12/100)

= 850 + 102

= 952

So he have to sell it at Rs. 952 to gain 12% profit.
