Answer» Correct Answer - Option 2 : 7 Calculation: In 2010, Let the salary of Ramesh, Ganesh and Rajesh be 6x, 5x and 7x Ramesh's salary increased by 25% during 2010 - 2015 = 6x × 125/100 ⇒ 7.5x But in 2015 the salaries ratio is 3 : 4 : 3 for Ramesh, Ganesh and Rajesh respectively We can see in 2015, the salary of Ramesh and Rajesh is the same which is in the given ratio.

Answer» Correct Answer - Option 2 : 7

Calculation:

In 2010, Let the salary of Ramesh, Ganesh and Rajesh be 6x, 5x and 7x

Ramesh's salary increased by 25% during 2010 - 2015 = 6x × 125/100

⇒ 7.5x

But in 2015 the salaries ratio is 3 : 4 : 3 for Ramesh, Ganesh and Rajesh respectively

We can see in 2015, the salary of Ramesh and Rajesh is the same which is in the given ratio.

So, In 2015, the salary for Rajesh should also be 7.5x

Now percentage increase in the salary for Rajesh during 2010 - 2015 = [(7.5x - 7x)/7x] × 100

⇒ (0.5/7) × 100

⇒ 50/7

⇒ 7.14%

∴ The percentage increase in Rajesh’s salary during this period is closest to 7%.
