@manisha
suppose his salary is Rs.100
20% of 100=20
100-20=80
60% of 80=48
80-48=32
10% of 32=3.2
32-3.2=28.8
hence
28.8 = 30
100 =?
we get
104.16
hence his salary is Rs.104.16

@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.
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.

Hello @Manish.
Total will be 100%
20% for rent.
60%for expenses.
10% for LIC.
TOTAL 90% OVER.
Know remaining spend 30.
10%=30 then 100%=300 total salary.

Most of them are wrong because firstly we use our original salary then 20%of that salary=remaining and 60% of that remaining and so on. @Aparna is right.

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.

No need to do these much calculation its very simple
consider his salary is X then
give 10% of his salary is 30rs from this
x*10/100=30
x/10=30
x=300
consider his salary is X then
give 10% of his salary is 30rs from this
x*10/100=30
x/10=30
x=300

Increase in 10 years =(262500 - 175000) = 87500.
Increase % in 10 years = (175000 * x/100)%,
x= 50%.
In 1 year = (50/10)%.
Ans = 5.
Increase % in 10 years = (175000 * x/100)%,
x= 50%.
