Why should we take 17,5000 in denominator why not 26,25000?

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.
