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

Hi @Jayakumar s
let the total number of votes = x
no.of votes cast = 75% of x
The valid votes = 98% of (no.of votes cast)
i.e 98% of (75% of x) (here 2% is invalid so (100-2)%=98%)
Then (A candidate got 75% of valid votes =9261)
75% of (98% of (75% of x) = > 75/100 * 98/100 *75/100 * x =9261.
= > (9261*100*100*100) / (75*98*75),
= > 9261000000 / 551250,
= >16800.

@ jagadeesh and reeta
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?? ....
1 decade = 10 years ........
