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%.

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.
