Q(1 – 5) Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –
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.
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

Q(1 – 5) Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –
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.
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.
Q(1 – 5) Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –
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.
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
Q(1 – 5) Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –
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.
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.
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.
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
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
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
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
From Statement I, If P = 100, A = 200 and SI = 200100=100
R= SI*100/P*T = 100*100/100*5 = 20%
From Statements II & III
R = 400*100/2000*1 = 20%
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
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 = [5008x]+18x/5x
All the given statements are Insufficient to answer the question.
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
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.
Q(11 – 20) Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –What is the profit earned by selling a bike for rupees 50000?
1) The cost price of 4 such bikes is equal to selling price of 3 bikes
2) 33.33% profit is earned by selling the bike.
From 1^{st} statement, 4*cp = 3*sp
4*cp = 3*50000, cp = 37500
From second statement, 50000 = [(100 + 100/3)/100]*c
We get cp = 37500

2) The simple interest accrued in 4 years is Rs. 2000.
From first statement, 2p = p*(r/100)*12
From second statement, 2000 = p*(r/100)*4

We can find the profit/loss percent but we cannot the amount of profit.
Q(11 – 20) Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the three statements and give answer: –
How long will machine B, working alone take to produce ‘y’ candles?
1) Machine A produces ‘y’ candles in 10 minutes
2) Machine A and Machine B working together produces ‘y’ candles in 4 minutes
From both statements,
1/A + 1/B = 1/4
So, 1/B = 1/4 – 1/10 = 6/40
B = 20/3 minutes

What is the speed of boat in still water?
1) It takes 4 hours to cover the distance between P and Q downstream
2) It takes 6 hours to cover the distance between P and Q upstream.
D = 4*(b+s) and D = 6*(bs)
So we can’t find the value of b

From second statement, we get
2400 = p*10/100*2
P = 12000
So CI = 12000*(1 + 10/100)^2 – 12000 = 2520
