Question

By what number should a given number be multiplied to decrease it by 25%?

Answer 1

Answer:

To increase the number by 25%.............it must be multiplied by 1.25

for ex. ::

let the number be x

25% of x

=(25/100)x

=0.25x

now x is increased by 25%............that means

x+25%= x+0.25x

=1.25x

so to increase any number by 25% it must be multiplied by 1.25 or (125/100).
