Answer:
40% . The single reduction together is 40%.
Step-by-step explanation:
Let the bicycle cost is x before reduced price.
First 25% is reduced and again 20% further reduced.
Let the single reduction is y% if the two reduction together are equal.
Solution,
Case .1
reduction cost
%


The cost of bicycle after reduction of 25% is

cost of reduction further reduction of 20%
%


The new cost of bicycle is further reduction of 20% is



Case.2
if single reduction is done new cost of cycle is equal
%=



%
single reduction of a cycle is 40%
2+2+9+0+8+1+2+3+4+5+6+7+8+9 is 66
To find the decimal divide the numerator by the denominator so
5/8=0.625 therefore as a decimal 5/8 =0.625
To find its percentage divide the numerator by the denominator and multiply by 100 so
5/8 *100=62.5 therefore as a percentage 5/8 is 62.5%
