The price of a cycle is rs 3,600 . its price is redused by 20% and again further redused by 1/4 . find the final price of the cycle after reduction.

price of cycle = 3600 Rs

if the price is reduced by 20%, the price will be:

3600 - (20/100*3600) = 3600 - (20*36)

                                      = 3600 - 720

                                      = 2880 Rs

if the price is further reduced by 1/4 (25%),

2880 - (25/100*2880) = 2880 - 720

                                      = 2160 Rs

Therefore, if the price is reduced first by 20% and this is further reduced by 25%, the final price after reduction will be 2160 Rs.
