Easy method to find the salary of the person.
20% on rent+60%on living +10% on L.I.C.+ remain 30rs on children.
20%+60%+10%+30rs=100%.
90% spent remain 30rs is equal to 10%. (.i.e 100%-90%=10%)
if 10 % =30rs ==> 100%=300 Rs.

By the way aparna's answer to manishas question is right. How can you reuse the total amount be it rs 100 or x again and again. Plus I have seen a lot of similar examples solved it in aparnas way. Check out for these kind of examples in MBA aptitude books.

1 decade = 10 years ........
here we need the average of percent rise ...
here the increment in percentage for 10 years is 50
so average = 50 / 10
= 5
got it?? ....
