Answers:
Directions (1-5):
Number of boys = 3/8 * 400 = 150 and number of girls = 250
Boys who speak only Hindi = 0.12 * 150 = 18
Girls who speak only English = 0.22 * 250 = 55
Students who speak only Hindi = 0.24 * 400 = 96
Hence Girls who speak only Hindi = 96 – 18 = 78
Hence Girls who speak both languages = 250 – 55 – 78 = 117
Boys who speak both languages = 18*6 = 108
Hence Boys who speak only English = 150 – 18 – 108 = 24
| Only English | Only Hindi | Both | Total | |
| Boys | 24 | 18 | 108 | 150 |
| Girls | 55 | 78 | 117 | 250 |
| Total | 79 | 96 | 225 | 400 |
1) Answer: b)
No. of boys who speak Hindi = 18 + 108 = 126
2) Answer: d)
78 girls speak only Hindi
3) Answer: a)
No. of students speaking English = 400-18 -78 = 304
4) Answer: e)
Required % = 78/96 * 100 = 81.25 %
5) Answer: c)
Required ratio = 108: 117 = 12: 13
Direction (6-10)
6) Answer: b)
In 2011, Export/Import = 0.8
7) Answer: d)
For 2014, E/I= 2.4 and for 2015, E/I = 1.8
50 = E1/2.4 + E2/1.8, so we can’t determine
8) Answer: d)
We don’t know the export or import of the company.
The given data is not sufficient to answer the given question
9) Answer: c)
E/I = 0.75
I = (4/3)*E
I – E = 50
4E/3 – E = 50,
So export = 150 crore
10) Answer: c)
Export/import = 2.4 = 24/10 = 12/5
So export = 12x and import = 5x
New ratio = 12x*(75/100) : 5x*(125/100) = 36/25 = 1.44
