= 2 × 3
=4×9 = 36
hence, time taken by both to meet again
LCM of 18 & 12 =36 minutes

Marginal product is defined as the incremental change in output that occurs due to a change in the input signals.
It is calculated on two steps:
1- Find the change that occurred to the outputs
2- Divide this change by the additional inputs
For the problem we have here:
Step 1:
old output = 100 dumplings
new output = 175 dumplings
change that occurred = 175 - 100 = 75
Step 2:
This change occurred as a result of adding 1 worker
Therefore:
marginal product = 75/1 = 75
Answer: (b)
You must first find a common denominator.
Change the fractions to the common denominator.
Then you add or subtract the fractions.
Finally, you may need to reduce the fraction.
Example 1:
Add
1/5 + 1/3
The least common denominator is 15.
Both denominators must become 15.
1/5 + 1/3 = 3/3 * 1/5 + 5/5 * 1/3 = 3/15 + 5/15 = 8/15
Example 2:
Subtract
3/8 - 1/3
The least common denominator is 24.
3/3 * 3/8 - 8/8 * 1/3 = 9/24 - 8/24 = 1/24
Both in addition and subtraction, you only add or subtract the numerators. The denominator of the answer is the common denominator.
