1).Points scored by player A = 4 ร 1 + 3 ร 2 + 1 ร 3 = 4 + 6 + 3 = 13
Alternatively:
Player A has overall accuracy of around 40% with quite a low accuracy of 3 pointers.
With total 20 attempts, assuming average score of 2 per attempt, approximate score would be
0.4 ร 2 ร 20 = 16.

8/10=0.8

12/15=0.8

14/18<0.8

19/24<0.8

Players B and C have the maximum accuracy of 80%.
Answer: b)
3).Total points = 25 ร 1 + 23 ร 2 + 13 ร 3 = 25 + 46 + 39 = 110
Points scored by player D = 8 ร 1 + 3 ร 2 + 3 ร 3 = 23
Percentage of points scored by player D =(23/110)ร100 โ 21%
Alternatively:
Approximately 20% of total attempts were made by player D with the same accuracy (approximately) as the other players except A, whose accuracy is quite low. Hence, player D must have scored approximately 20% of total points.
Answer: b)
4).Number of points scored through 2pointers = 2 ร 23 = 46
Percentage of points through 2pointers = (46/110)ร100 โ 42%.
Answer: c)
5).Total points scored from 3pointers = 13 ร 3 = 39
Total points scored from 2pointers = 23 ร 2 = 46
Required percentage = [(4639)/46] ร 100 โ 15.2%.
Answer: c)
6).Total population of each of the states is not given. Hence data inadequate.
Answer: d)
7).9/16 part of 16% = 6.3 million
= 9% = 6.3 million
10/21 part of 84% ie 40% = (6.3/9)ร40 = 28 million.
Answer: b)
8).At first glance, data seems inadequate for the question.
Let total population of state A and state D be x and y respectively.
Female population above poverty line in state A = 5/9 part of 72% of x = 40% of x.
Female population above poverty line in state D = 10/21 part of 84% of y = 40% of y.
According to the question,
40% of x โ 40% of y = 3.6
= 40% of (x – y) = 3.6
= x โ y = 9 million
Note: If percentages are different then we canโt solve the problem.
Answer: a)
9).Percentage male population below poverty line in state C = 6/11 part of 44% = 24%
and that in state E = 5/12 part of 24% = 10%
Combining both states, we have 15% male population below poverty line.
It means that 15% is the weighted mean of 10% and 24%.
C E
24% 10%
15%
5 9
Therefore, total populations of C and E are in the ratio 5 : 9.
Now, % male population above poverty line in state C = 13/28 part of 56% = 26%
and that in state E = 9/19 part of 76% = 36%.
Required % = [(26ร5+36ร9)/(5+9)] = (130+324)/14 = 454/14 = 32.4%
Answer: b)
10).Let the total population of state C and state B be x and y respectively.
According to the question,
15/28 part of 56% of x> 7/16 part of 64% of y
= 30% of x> 28% of y
= x> y or x< y or x = y.
