Answer»

Given:Ratio of two fans = 16:23multiply by common factor xthe prices will be 16x & 23x

AFTER TWO YEARSfirst fan increaed by 10 % = 0.1*16x

price of the fan =16x+1.6x= 17.6x

increase in other fan = Rs. 477price = 23x+477

352x=11(23x+477)

352x=253x+5247352x-253x=5247

99x=5247

x=53Therefore, Price of one fan = 53*16 =Rs. 848
