Sample Question 4
Data
Hard • Quantitative Aptitude Test
Marriages in 2000 if 1965-2000 rate of increase remains constant?
A
1.8 million
B
2.0 million
C
2.2 million
D
2.7 million
E
2.9 million
โ Correct Answer: D - 2.7 million
๐ Step-by-Step Solution & Conceptual Rationale:
Increase over 3 years (1965 to 1968):
\(21.3 - 20.8 = 0.5\text{ units}\)
Annual rate of increase: \(\frac{0.5}{3} \approx 0.1667\text{ units per year}\)
Time span from 1965 to 2000: \(2000 - 1965 = 35\text{ years}\)
Total projected increase by 2000: \(35 \times 0.1667 \approx 5.83\text{ units}\)
Projected value in 2000: \(20.8 + 5.83 = 26.63\text{ units}\)
Converting this back to the scale of millions yields approximately 2.66 million, which rounds cleanly to 2.7 million.

Sample Question 5
Data
Hard • Quantitative Aptitude Test
How many marriages occurred as the final approximate total in three different years?
A
1.7 million
B
1.3 million
C
1.55 million
D
1.45 million
E
1.9 million
โ Correct Answer: A - 1.7 million
๐ Step-by-Step Solution & Conceptual Rationale:
If you look at the horizontal level of 17 (representing 1.7 million marriages) on the y-axis, the line touches or crosses this exact value at three different points in time:
1953: The graph starts right at approximately 1.7 million.
1956: The first sharp peak returns exactly to that same height of 1.7 million.
1958โ1959: As the line makes its final sharp upward climb towards the 20 mark, it crosses the 1.7 million threshold for the third time.

Sample Question 6
Data
Hard • Quantitative Aptitude Test
Govt collection 1966: Rs 200/marriage, Rs 100/birth, Rs 20/young person?
A
Rs. 260 million
B
Rs. 480 million
C
Rs. 820 million
D
Rs. 1160 million
E
Rs. 1500 million
โ Correct Answer: D - Rs. 1160 million
๐ Step-by-Step Solution & Conceptual Rationale:
Number of Marriages (Top-Right Graph):
In 1966, the marriage value is approximately 21 (which corresponds to 2.1 million marriages).
\(\text{Collection from Marriages}=2.1\text{ million}\times \text{Rs }200=\text{Rs }420 \text{ million}\)
Number of Births (Bottom Graph):
In 1966, the birth line settles right at 3.55 million births.
\(\text{Collection from Births}=3.55\text{ million}\times \text{Rs }100=\text{Rs }355\text{ million}\)
Number of Young People (Top-Left Graph):
In 1966, the line sits at approximately 19.25 million young people.
\(\text{Collection from Young People}=19.25\text{ million}\times \text{Rs }20=\text{Rs }385\text{ million}\)
Total Government Collection:
\(\text{Total Collection}=420+355+385=\text{Rs }\mathbf{1160}\text{ million}\)
In 1966, the marriage value is approximately 21 (which corresponds to 2.1 million marriages).

Hard • Quantitative Aptitude Test
Central angle of the sector for Industrial Insurance (1992)?
A
28
B
30
C
32
D
34
E
36
โ Correct Answer: E - 36
๐ Step-by-Step Solution & Conceptual Rationale:

Sample Question 8
Data
Hard • Quantitative Aptitude Test
If 50m paid in 2001, how many millions were from Group insurance?
A
13
B
14.5
C
16
D
17.5
E
19
โ Correct Answer: D - 17.5
๐ Step-by-Step Solution & Conceptual Rationale:
Total growth over the 10-year period (1992 to 2002): \(35\% - 25\% = 10\%\)
Annual rate of increase: \(\frac{10\%}{10\text{ years}} = 1\%\text{ per year}\)
Projected percentage for 2001 (9 years after 1992): \(25\% + (9 \times 1\%) = 34\%\)
Amount from Group Insurance (out of 50 million):\(50\text{ million}\times 34\%=50\times 0.34=17.0\text{ million}\)
Among the given multiple-choice options, 17.5 (D) is the closest standard approximation used for this dataset.
