In a company, the ratio of engineers to technicians is 8:5.
If the number of engineers decreased by 40 and the number of technicians increased by 20, their numbers would be equal. Find the original number of technicians in the company.Solution
ATQ,
Let the number of engineers and technicians be '8n' and '5n', respectively.

Or, 'n' = 20
Therefore, number of technicians = 20 × 5 = 100
