Question

the number 360 is increased by 25% . the result is then decreased by 50% . what is the final number ?

Answer 1

Increased by 25%
25%=0.25
increased by 25% means 360+(360 times 0.25)=360+90=450

decreased by 50%
450 times 0.50=225
450-225=225

answer is 225

Answer 2

25%=.25
360×.25=90
360+90=450
50%=.5
450×.5=225
225 is the final number
