Question 550378: The ratio of the prices of two fans was 16:23.Two years later,when the price of the first fan had risen by 10% and that of the second by Rs 477,the ratio of their prices became 11:20.Find the original prices of two fans.
You can put this solution on YOUR website! Ratio of two fans = 16:23
multiply by common factor x
the prices will be 16x & 23x
AFTER TWO YEARS
first fan increaed by 10 % = 0.1*16x
price of the fan =16x+1.6x= 17.6x
increase in other fan = Rs. 477
price = 23x+477
cross multiply
352x=11(23x+477)
352x=253x+5247
352x-253x=5247
99x=5247
x=53
Price of one fan = 53*16 =Rs. 848
price of second fan = Rs. 1219
