Question

If one-eighth of a pencil is black, half of the remaining is yellow and the remaining 3.5 cm is blue, then the total length of the pencil is (in cm)​

Answer 1

Answer:

Let the length of the pencil be 8x cm.

Now, x cm of it is black.

Remaining length = 8x - x = 7x cm.

Out of 7x cm, 3.5x cm is yellow in colour.

Remaining = 3.5x cm.

=> 3.5x = 3.5

=> x = 1

Therefore, length of pencil = 8 cm
