@Bunny.
Here,
1 decade = 10 years
Therefore, to find out the increased average percentage for( per year) would be always divided by 10. That's why 50 which is increased Percentage is then divided by 10 to find out the increased average percentage for PER YEAR!

20% for rent.
60%for expenses.
10% for LIC.
TOTAL 90% OVER.
Know remaining spend 30.

We use the formula 262500 = 175000(1+ R/100)^n.
Where n = 10, and the value of R turns out to be 4.138 which is 4.138%. So none of these is the answer.

@Aparna.
You are 100% wrong. Because you should take 60% of 100Rs, not 60% out of 80.
Take the % out of 100Rs, not out of remaining cost.

Easy method:
Salary be x.
Total expenditure is 20%+60%+10% = 90%.
Remaining 10%,
10% of x = 30rs,
10x = 3000,
X = 300rs,
Salary is 300rs.
Salary be x.
Total expenditure is 20%+60%+10% = 90%.
Remaining 10%,
10% of x = 30rs,
10x = 3000,
X = 300rs,
Salary is 300rs.
