In the recent, climate conference in New York, out of 700 men, 500 women, 800 children present inside the building premises, 20% of the men, 40% of the women and 10% of the children were Indians. Find the percentage of people who were not Indian?

A. 77%

B. 73%

C. 79%

D. 83%

Answer: Option C

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%

    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%
