Botany, Mathematics, Physics and Statistics. The ratio of the number of boys and girls among them is 6:8.30% of the total girls are doing graduation in Zoology and 20% of the total girls are doing graduation in Statistics. The total number of students doing graduation in Botany is 220. 250 students are doing graduation in Mathematics. The ratio of the number of girls and the number of boys doing graduation in Statistics is 2:1.20% of the total number of boys are doing graduation in Botany. The ratio of the number of girls and that of boys doing graduation in Mathematics is 2:3. There are an equal number of boys and girls doing graduation in Physics. 290 students are doing graduation in Zoology.

Answer :
Number of boys = 600Number of girls = 800
Girls

Boys


Zoology

30 x 8 = 240

290 – 240 = 50

Botany

220 – 120 = 100

20 x 6 = 120

Mathematics

2/5 x 250 = 100

3/5 x 350 = 150

Physics

200

200

Statistics

20 x 8 = 160

160/2 = 80

1. 3;
Required answer = 200 + 200 + 160 + 80 = 640
Required answer = 200 + 200 + 160 + 80 = 640
2. 4;
Required ratio = 150 : 100 = 3:2
Required ratio = 150 : 100 = 3:2
3. 1;
Required difference = 100  50 = 50
Required difference = 100  50 = 50

Required percentage = 160/200 x 100 = 80%
Required percentage = 160/200 x 100 = 80%
