Question

the rent of a house was increased from 3000 to 4500 find the percentage​

Answer 1

The increased value = (4500-3000)

                                  = 1500

So, the increased rate = (1500/3000)*100

                                     = (1*100/2)

                                     = 50%

Answer 2

first

we will subtract the new value by the old

4500-3000=1500

then

1500/3000×100

=50℅
