### Solution(By Examveda Team)

Number of Indians men present there = $$\frac{{700 \times 20}}{{100}} = 140$$
Indian women = $$\frac{{500 \times 40}}{{100}} = 200$$
Indian children = $$\frac{{800 \times 10}}{{100}} = 80$$
Total member present in climate conference = 700 + 500 + 800 = 2000
Total Indian = 200 + 140 + 80 = 420
Hence, % of Indian present there = $$\frac{{420 \times 100}}{{2000}} = 21\%$$
% of people who were not Indian = 100 - 21 = 79%

1. Number of Indians men present there = 700*20/100 = 140
Indian women = 500*40/100 = 200
Indian children = 800*10/100 = 80.
Total member present in climate conference = 700+500+800 = 2000
Total Indian = 200+140+80 = 420
Hence, % of Indian present there = 420*100/2000 = 21%
% of people who were not Indian = 100-21= 79%

2. % of people who were not Indian = 100-42 = 79%. ??????how??

100-21=79!!!!
