Question

1/ 3 part of the length of a bamboo is coloured red and 1/ 5 part of it is coloured green and the remaing 14 m length is coloured yellow. Let's find the length of the bamboo

Answer 1

The length of bamboo=y= (y/3)+(y/5)+14m

So, (5y/15) + (3y/15)+14m= (15y/15)

= (8y/15)+14m=(15y/15)

=14m= (15y-8y)/15

14m=(7y/15)

14×15= 7y

7y= 210

y= 210/7

y= 30m

Therefore, the length of bamboo= (30/3)+(30/5)+14m

= 10m+6m+14m

= 30m

Hence, the length of bamboo is 30m.

Hope it helps you.
