An inspector found 40 defective batteries during an inspections. If this is 2.5% of the total number of batteries inspected, how
many batteries were inspected?
1 answer:
Answer: 1600batteries
Step-by-step explanation:
Let the number of inspected battery be y
2.5% of y = 40
5/2% of y = 40
Change 5/2% to fraction
5/200 × y = 40
5y/200=40
Cross multiply
5y= 40×200
5y=8000
y=8000÷5
y=1600
The total number of battery inspected is 1600.
