@Manisha.
Take total salary = 100%.
100% - 20% - 60% - 10%,
= 10%.
According to the question:
10%= 30, then,
100%=x,
By cross multiplication, we got x= 300.
Which was his total salary.

1 decade = 10 years.
Population increased as 175000 to 262000 in decade;
x = (262000-175000) = 87500.
increase percentage =(x/175000*100) = 50%.
The required average of decade from increased percentage = [increased percentage / decade] = (50/10)% = 5%.

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

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).

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