Solutions
S1. Ans.(d)
Sol. The data gives brand wise ownership by age, not market share details. Hence, the question cannot be answered.
S2. Ans.(b)
Sol. 90% of the total BPL sets are over one year old.
S3. Ans.(b)
Sol. 55% of the total BPL sets are over five years old.
35% of the total BPL sets are over 2 years old.
Required % = (55-35)/35 * 100 = 57.14% more
S4. Ans.(c)
Sol. Required answer = 15% of 800,000 = 1,20,000
S5. Ans.(c)
Sol. Take the weighted average. It can be seen that the approximate ratio of boys to girls is 4 : 1. Hence using alligation, the answer will be
S6. Ans.(a)
Sol. Visual ratio comparison question. It is clearly the case of Business Management.
S7. Ans.(b)
Sol. (261-160)/160 = 101/160 = 63.1%
S8. Ans.(d)
Sol. 25/85 = 5/17 = 30% (approx.). Hence none of these.
S9. Ans.(c)
Sol. (611 - 145)/145 = 466/145 = 321.4%
S10. Ans.(b)
Sol. Visual interpretation of the age groups given, 15 -35 has 35% (65 - 30), which is the max.
S11. Ans.(b)
Sol. 47.75% of 400,000 = 191000
S12. Ans.(c)
Sol. 65% corresponds of 40 million and correspondingly 5.12% (5.12 = 98.87 - 93.75) corresponds to 3.15 million.
S13. Ans.(b)
Sol. 6.25% people belong to the age group 56 and above, and this corresponds to 20 million, then 3.5% (difference between the respective age groups referred to) = 11.2 million.
S14. Ans.(b)
Sol. 3% is 3.9 million, hence 100% will be 130 million.
S15. Ans.(c)
Sol. 35% of the population is between 15-35 and 35% is above 35. Hence the answer is 1:1.
