Answer:
Bottle number 24 will be the first to get a green label and a pink cap.
Step-by-step explanation:
See,
We get green label at every 8th bottle
And a pink cap at every 6th bottle.
So if we need a bottle with green label and pink cap then that bottle number should the common number that is divisible by both 8 and 6.
Since 24 is the very first number which can be divided by both 8 and 6.
Hence bottle number 24 will be the first to get a green label and a pink cap.
