If 1/8 of a pencil is black 1/2 of the remaining is white and the remaining 3 1/2 is blue find the total length of the pencil?

Answer»

Let the total length be xm 

Then black part =x/8cm 

The remaining part=(x-x/8)cm=7x/8cm 

White part=(1/2 *7x/8)=7x/16 cm 

Remaining part=(7x/8-7x/16)=7x/16cm 

7x/16=7/2 

x=8cm
