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
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

1). Answer: a)
Marks scored by Rima in Mathematics = (92/100) * 250 = 230
Marks scored by Isha in Mathematics = (78/100) * 250 = 195
Marks scored by Akansha in Mathematics = (60/100) * 250 = 150
Marks scored by Ishant in Mathematics = (64/100) * 250 = 160
Required average = (230 + 195 + 150 + 160)/4 = (735/4) =183.75
2). Answer: c)
Let total marks in Hindi and Social sciences be H and S respectively.
Marks scored by Rima in Hindi = (80/100) * H
160 = (80/100) * H
H = 200.
Marks scored by Rima in Social sciences = (74/100) * S
222 = (74/100) * S
S = 300.
Marks scored by Isha in Hindi = (58/100) * 200 = 116.
Marks scored by Akansha in Social sciences = (70/100) * 300 = 210.
Required ratio = (116/210) = 58/105
3). Answer: d)
Marks scored by Rima in English = (70/100) * 200 = 140
Marks scored by Isha in English = (65/100) * 200 = 130
Marks scored by Akansha in English = (50/100) * 200 = 100
Marks scored by Sneha in English = (72/100) * 200 = 144
Marks scored by Karan in English = (58/100) * 200 = 116
Marks scored by Akash in English = (84/100) * 200 = 168
Marks scored by Ishant in English = (70/100) * 200 = 140
Required average= (140 + 130 + 100 + 144 + 116 + 168 + 140)17
= (938/7) = 134.
4). Answer: e)
As maximum marks of Science and Mathematics are not given so answer cannot be determined.
5). Answer: c)
Let maximum marks in Science = Maximum marks in Mathematics = M
Total marks scored by all 7 students in Science
= (95% + 82% + 65% + 72% + 46% + 90% + 80%) * M
= (530%) * M
Total marks scored by all 7 students in Mathematics
= (92% + 78% + 60% + 76% + 59% + 90% + 64%) * M
= (519%) * M Required ratio
= (530/519)
Marks scored by Rima in Mathematics = (92/100) * 250 = 230
Marks scored by Isha in Mathematics = (78/100) * 250 = 195
Marks scored by Akansha in Mathematics = (60/100) * 250 = 150
Marks scored by Ishant in Mathematics = (64/100) * 250 = 160
Required average = (230 + 195 + 150 + 160)/4 = (735/4) =183.75
