All 4 stages span a total of 4 weeks or 28 days.
Egg - 2 days
Larva - 7 days
Pupa - 5 days
Adult - 14 days
This means that the larva exists for 7/28 = 25% of the time.
So, 25% of the randomly selected developing bees would be larva.
25% of 200 is 50. So, the answer is A.
Edit: The question is ambiguous. If by developing bees they exclude all the adult bees, then larva exist for 50% of the time and the answer would be 100.
The original number is 140
for this problem you will need to do a proportion
40/100 = 56/x
40x = 56 * 100
40x = 5600
40x/40 = 5600/40
x = 140
hope this help with other problems
Solution of 8 x 4 - 4 divided by 2 +1 is 9.33
<h3><u>Solution:</u></h3>
Given that,
8 x 4 - 4 divided by 2 +1
We have to compute the above equation
Let us write the given sentence mathematically:

Let us BODMAS rule to solve the above expression
According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.
So let us first perform multiplication of 8 and 4 in numerator

Now we can perform addition of 2 and 1 in denominator

Now we can perform subtraction of 4 from 32 in numerator

Now perform division of 28 by 3

Thus solution of 8 x 4 - 4 divided by 2 +1 is 9.33
Well I really don’t know but good luck w this I hope you pass school is so stressful
