It's like compound interest. Here, Every year more people are coming into existent. so we need to count interest rate on increased capital. Formula for compound interest is:
Increased capital = initial capital(1+rate)^year.
Increased capital = initial capital(1+rate)^year.

@manish - the easiest way is...
Total expenses %age is 20%+60%+10%=90% .. so remaining is 10% ..
That remaining 10% is Rs 30 ,so
100% will be (30/10)*100= Rs 300 .. simple.

Percentage formula.
% = [final value-intial value/intial value] * 100.
% = 87500/17500 * 100.
= 5 is the ans hence proved.

Suppose man's salary =100 Rs.
20%=20 Rs rent,
60% =60 Rs Expense,
10% =10 Rs LIc,
so left amount for education=100-(20+60+10)=10,
10% left ie 10 Rs of 100 %,
10%= 30(In qs),
1% =30/10,
100% =30*100/10=300(salary).
20%=20 Rs rent,
60% =60 Rs Expense,
10% =10 Rs LIc,
so left amount for education=100-(20+60+10)=10,
10% left ie 10 Rs of 100 %,
10%= 30(In qs),
1% =30/10,
100% =30*100/10=300(salary).

@Manisha.
20+60+10=90 so remaining is 10%. They said the remaining salary 30.
So 9*30=270.
Total salary=270+30=300.
20+60+10=90 so remaining is 10%. They said the remaining salary 30.
So 9*30=270.
Total salary=270+30=300.
