You can't the answer is 2 because 20 goes into 10 twice
There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171
The rate of the machine is 10 boxes per min.
Step-by-step explanation:
Given,
A machine can make 150 boxes in 15 min
To find the rate of the machine
Meaning to find the number of boxes machine it can make in 1 min
We will apply unitary method.
In 15 min it makes 150 boxes
In 1 min it makes (150÷15) boxes = 10 boxes
Hence the rate is 10 boxes per min.
