Hence first mechanic worked for 15 hours and second mechanic worked for 5 hours.
<h3>What is ratio and proportion?</h3>
When comparing two quantities of the same kind, ratio is utilized.
For two numbers, a and b, the ratio formula is written as a: b or a/b.
Two or more ratios are said to be in proportion if they are all equal.
Fractions are the foundation of the concepts of ratio and proportion.
Let x is the number of hours the first mechanic worked and y is the number of hours the second mechanic worked.
∵x+y = 20
x = 20 - y
115x+100y = 2225
115(20-y) + 100y = 2225
2300 - 115y +100y = 2225
15y = 75
y = 5 hours
∴ x = 20-5
x = 15 hours
