From the question we know that the machine fills 3 small bottles per second and 5 big bottle in every 6 seconds and then it further tells us that the machine worked for 1 minute and then bottles which the machine filled in that time were arranged in 10 crates, and each crate have same number of small and same number of large bottles.
So from here we can calculate the total number of bottles filled during the time period.
Small Bottle: 3*60 = 180 bottles
Large Bottle: (5/6)*60 = 50 bottles
Now after knowing the total number of bottles we have to find the number of bottles per crate. So for that we fill divide the total number of bottles with total number of crates.
Small Bottle per crate: 180/10 = 18 bottle in every crate
Large Bottle per crate: 50/10 = 5 bottle in every crate
So the answer for this is Option 'C' for Small Bottles and Option 'B' for Large Bottles.
Bunuel
A water bottling machine is designed to fill two types of bottles—small and large—at the same time.
It fills small bottles at a constant rate of 3 per second and large bottles at a constant rate of 5 every 6 seconds.
In one minute of continuous operation at these rates, the machine fills small and large bottles that are packed into exactly 10 shipping crates, with each crate containing the same number of small bottles and the same number of large bottles.
