Answer: 10%
Explanation:
The formula to calculate the simple interest (I) is given by :-
Final amount :
Given : The simple interest earned on a certain amount is double the amount when invested for 10 years.
i.e A = 2P
Put this in equation (2), we get
Put the value of I in (1), we get
Since t=10 years {given} , then

In percent , 
Hence, the interest rate is being offered = 10%
Answer:
production at this point is technically inefficient.
Explanation:
Efficient production processes requires a producer to either minimise the inputs they are using at a given output or maximise output level at a given input level.
Technical inefficiency is when input is not minimised or output maximised.
In the given instance the fixed cost (airplane) remains unchanged. However crew members can be variable.
