Explanation:

Explanation :
Grant from central government = 30% of 40 crore = 12 crore
After increase 10% = 110% of 12crore = 13.2 crore
foreign contribution = 20% of 40 crore = 8 crore
After 10% decrease in foreign contribution = 90% of 8 crore = 7.2 crore
Total increase in donation = [13.2 + 7.2] – [12 + 8] = 0.4 crore
Gradual increase in expenditure = (39/40)*40.4 = 39.39 crore
Gradual increase in A =(10/39)*39.4 = 10.10 crore
% increase = (0.10/10)*100 = 1%
