From the given question we know that 21% = 63 cans
Now it is important to find out the number of cans that will make 1%
Then
21% = 63 cans
so
1% = (63/21) cans
= 3 cans.
Now we have to find out the number of cans in 46%
We know
1% = 3 cans
so
46% = (3 * 46) cans
= 138 cans
We also have to find the number of cans in 33%
So
33% = (3 * 33) cans
= 99 cans
