The Correct Option is B
Solution and Explanation
Their salaries in 2010 were 6x, 5x, and 7x, respectively.
Subsequently, in 2015, their salaries became 3y, 4y, and 3y.
The relationship \(3y = 1.25\times6x\) is established, leading to the conclusion that y is equivalent to 2.5x.
Consequently, Rajesh's salary in 2015 is determined to be 7.5x.
The calculated percentage increase in Rajesh's salary from 2010 to 2015 is approximately 7%.
