A. If the data in statement I alone is sufficient to answer the question.
B. If the data in statement II alone is sufficient to answer the question.
C. If the data either in statement I alone or statement II alone are sufficient to answer the question.

1. A car dealer sold 80% of the cars in its inventory during September. What was the total revenue from the sales of cars?
I. All but 60 cars in the showroom inventory were sold during September.
II. Cars were sold for an average price of Rs.4.5 lakh during September.
Answer – E. if the data in both the statements I and II together are necessary to answer the question
Explanation :
Total no of cars in September = x
From Statement I – 20% of x = 60 (Cars that are not sold)
x = 300
80% 0f 300 =240
From Statement II – Price of a car = Rs.4.5 lakh
From Statement I & II – The total revenue from the sales of cars = 240 * 4.5 lakh = 1080 lakh

2. Did Incumbent P get over 60% of the vote?
I. Challenger M got 39% of the vote
II. Incumbent P got 40000 of the total votes cast
Answer – A. If the data in statement I alone is sufficient to answer the question.
Explanation :
From Statement I, P got 61% of the vote which is over 60%.

3. How much money did X invest?
I. An increase in the Simple Interest from 39/8 % to 41/8 % per annum increases his yearly income by 25%.
II. The sum invested gets doubled, when invested at 8% per annum for 25/2 year.
Answer – A. If the data in statement I alone is sufficient to answer the question.
Explanation :
Invested amount – x
From Statement I, Increased Rate of interest = (41/8) – (39/8) = 2/8 =1/4
x*(1/4)*(1/100) = 25 => x=10000
From Statement II, we can’t find x.

4. For a certain bottle and cork, what is the price of the cork?
I. The combined price of the bottle and the cork is Rs.95
II. The price of the bottle is Rs.75 more than the price of the cork.
Answer – E. if the data in both the statements I and II together are necessary to answer the question.
Explanation :
From Statement II, Let the price of cork be x, then the price of the bottle = (x+75)
From Statement I, combined price bottle and cork = Rs.95
x+(x+75) = 95 => 2x + 75 = 95 => x = 10

5. What is the weighted average of marks obtained by Deepak?
I. Maths, Science and English have weights 5, 4 and 3 respectively.
II. Simple Arithmetic mean of Maths and science is 140, which is twice the average of Science and English.
Answer – D. If the data given in both I and II together are not sufficient to answer the question.
Explanation :
In Statement I, Only weights of subjects are given
(M+S)/2 =140 => M + S = 280
(S+E)/2 = 2(140) => S + E = 560 We can’t find the marks in Maths, Science and English.

6. In how many days 10 women can finish the work?
I. 10 men finish the work in 6 days.
II. 10 women and 10 men finish the work in 24/7 days.
III. If 10 men work 3 days and after that 10 women are deployed to work for men, the rest work is finished in 4 days.
A. I and II
B. I and III
C. Any two of three
D. II and III
E. None of the Above
Answer – C. Any two of three
Explanation :
From I and II, 10 women’s work in 1 day = (7/24 – 1/6) = 1/8
10 women can finish the work in 8 days.
From II and III
(1/x + 1/y) = 7/24
(3/x + 4/y) = 1
=> y = 8 days
From I and III – (3/6 + 4/y) = 1 => y= 8 days

7. What is the cost of flooring the rectangular hall?
I. Length and Breadth of the hall are in the ratio of 3:2
II. Length of the hall is 48m and cost of flooring is Rs.850 per sq m.
III. Perimeter of the hall is 160m and cost of flooring is Rs.850 per sq.m
A. I and II
B. I and III
C. Only III
D. I and either II or III
E. Any two of three
Answer – E. Any two of three
Explanation :
From Statements I and II length 3x = 48 => x = 16m
length = 48m, Bredth = 32m, Area = 48*32
Cost of flooring = 48*32*850 = Rs. 1305600
From Statements II and III, l= 48m, b=32m
Cost of flooring = 48*32*850 = Rs. 1305600
From Statements I and III,
2(l+b) = 160
2(3x + 2x) = 160 x=16
length = 48m, Bredth = 32m, Area = 48*32
Cost of flooring = 48*32*850 = Rs. 1305600

8. What is the rate of interest per cent per annum?
I. An amount doubles itself in 5 year on SI
II. Difference between the CI and SI earned on a certain amount in two years is Rs.400
III. SI earned per annum is Rs.2000
A. I and II
B. I and III
C. Only III
D. Either I or II and III
E. Any two of three
Answer – D. Either I or II and III
Explanation :
From Statement I, If P = 100, A = 200 and SI = 200-100=100
R= SI*100/P*T = 100*100/100*5 = 20%
From Statements II & III
R = 400*100/2000*1 = 20%

9. How much time will the train A take to cross another train B running in opposite direction?
I. Train A crosses a signal pole in 6s
II. Ratio of the speed of trains A and B is 3:2
III. Length of two trains together is 500m
A. Only I
B. Only II
C. Only III
D. Only I and II
E. All the given statements are Insufficient
Answer – E. All the given statements are Insufficient
Explanation :
From Statement I, Time taken by Train A crosses a signal pole = 6s
From Statement II, Speed of Train A and Train B = 3x and 2x, Relative speed = 5x
From Statement I and Statement II. A Train’s length = 18x
B Train’s length = 500 – 18x
Time taken by A to cross B = [500-8x]+18x/5x
All the given statements are Insufficient to answer the question.

10. An Express Train leaves Delhi at 4pm for Mumbai, At what time will it reach Mumbai?
I. It maintains the average speed of 110 kmph
II. It has four stoppages of 10 min each between Delhi and Mumbai
III. It covers 250km before each stoppage
A. Only II
B. Only II
C. Only III
D. All the given statements are Sufficient
E. All the given statements are Insufficient
Answer – D. All the given statements are Sufficient
Explanation :
From statement I and II, Distance covered from Delhi to Mumbai Stoppage = 250*5 = 1250km
From Statement I, Time = Distance/speed = 1250/110
So all the three statements required to answer this question.
