Question

In a box 40% pencil in their and 150 pens, find the total
pen and pencil in
a box .
​

Answer 1

40% are pencil so the percentage of pen= 100-40

=60%

so 60% is equal to 150

so total number of item= (100/60)*150

=250

so number of pencil= total item-number of pen

=250-150

=100

so total number of pencil=100
