A shopkeeper sold an item at a loss of 20% and received 20000/-. What was the cost price of the item?
Let CP = x
(1-0.2)(x) = 20000
(0.8)(x) = 20000
x = 25000/-
So the answer is option B.
A college celebrated a festival for five days. The average daily attendance in those five days was 678 while the average attendance in the last four days of the festival was 679. What was the attendance on the first day of the festival?
Total attendance in 5 days = 678*5 = 3390
Attendance in 1st day + attendance in last 4 days = attendance in 5 days
x + 4(679) = 3390
x + 2716 = 3390
x = 674
So the answer is option D.
Rupesh started his journey of 150km with the speed of 45kmph, after travelling for 2hrs, he realized that he is left with 1hr to reach his destination. Find his new speed if he reached his destination on-time.
Total distance = 150km
Distance covered by him in 2 hrs = 45*2 = 90km
Remaining distance = 150-90 = 60km
So the answer is option C.
Find tan θ, if secθ = 13/12 ?
It is known that 0 < θ < 90
So the answer is option B.
Find the HCF of 1/2, 2/3 & 3/4 ?
H.C.F of fractions = H.C.F of numerators / L.C.M of denominators = (HCF of 1, 2, 3)/(LCM of 2, 3, 4) = (1)/(12) = 1/12
P and Q together can complete a piece of work in 8 days, Q alone can complete the same work in 12 days.In how many days can P alone complete the same work?
Let total work = LCM of 8 and 12 = 24 units
Efficiency of P&Q; = 24/8 = 3
Efficiency of Q = 24/12 = 2
Then efficiency of P = 3-2 = 1
P alone can complete 24 units of work in 24/1 = 24 days
So the answer is option A.

Find the perimeter of a rectangle whose length is 9 cm and breadth is equal to the side of a square of area 36 sq.cm ?
Length of rectangle = 9 cm
Breadth = side of square = √36 = 6 cm
Perimeter = 2(l+b) = 2(9+6) = 30cm
So the answer is option B.
4 walls of a house of height 4m, width 6m and length 8m are to be painted. What is the total expenditure if the painter charges Rs.1.5 per sq.m ?
Lateral surface area = 2h(l+b) = 2(4)(6+8) = 112sq.cm
Cost of painting = 112*1.5 = 168
So the answer is option A.
Sampath sold an item to sharath for 2500/- and earned a profit of 100/-. What is the profit percentage in this transaction?

BA : CE :: DI : ?
B is the first consonant and A is the first vowel.
C is the second consonant and E is the second vowel.
D is the third consonant and I is the third vowel.
Therefore, the next term must be composed of the fourth consonant and the fourth vowel - F and O respectively. Therefore, option C is the right answer.
elect the option that is different from the other 3 options:
Kiwi, Ostrich and Emu are flightless birds. Peacock can fly. Therefore, option D is the right answer.

Which of the following words cannot be formed using the letters of the word ‘SCHADENFREUDE’?
Diffuser has 2 F’s. SCHADENFREUDE has only one F. Clearly, DIFFUSER cannot be made by shuffling the letters of SCHADENFREUDE. Hence, option D is the right answer.
If DRY is coded as 1800 and BAT is coded as 40, the code of which of the following words is 200?
The code for a word is the product of the position of the letters of the word in the alphabetical series.
DRY - 4*18*25 = 1800
BAT - 2*1*20 = 40
Let us evaluate the options using the same logic.
GATE - 7*1*20*5 = 700
DEBT - 4*5*2*20 - 800
BEED - 2*5*5*4 - 200
DATE - 4*1*20*5 - 400
Therefore, option C is the right answer.
If ‘+’ means ‘-’, ‘-’ means ‘*’, ‘*’ means ‘/’ and ‘/’ means ‘+’, then what is the value of the following expression?
13 - 13 / 3 - 63 * 9 + 2 -5
Let us replace the symbols with the actual operators.
13 - 13 / 3 - 63 * 9 + 2 -5 = 13 * 13 + 3*63/9 - 2*5
Applying BODMAS rule, we get, 169 + 3*7 - 10 = 180
Therefore, option B is the right answer.
Which of the following options should come in the place of x,y and z in that order in the grid if it is known that all the numbers from 1 to 9 are used exactly once and the sums of the elements along both the diagonals are equal to the sum of the elements of the first column?
Each number is used only once and the sums of numbers along both the diagonals are equal.
6 + z + y = 2 + 8 + z
=>y = 4
6 + 1+ 8 = 6 + z + 4
=> z = 5 and x = 3.
(x,y,z) = (3,4,5).
Therefore, option A is the right answer.
Consider the given statements to be true even if they are at odds with generally known things. Based on the statement, evaluate which of the conclusions follow:
No tree is a herb.
All herbs are shrubs.
Some shrubs are trees.
I: All shrubs being trees is a possibility.
II: All trees being shrubs is a possibility.
The given statements can be expressed diagrammatically as follows without violating any of the conditions.
Shrubs that are herbs cannot be trees as no herb is a tree. Therefore, conclusion I does not follow.
Trees and herbs can be 2 disjoint subsets of Shrubs. Therefore, conclusion II follows.
Only conclusion II follows. Therefore, option B is the right answer.
Which of the following options will bear the same relationship as the words given in the first part of the question?
Belgium: glass :: Italy : ?
Belgium is famous for glass products. Similarly, Italy is renowned for its marbles. Therefore, option C is the right answer.

371 : 4 :: 442 : ?
A family consists of 4 members - A, B, C and D. There are 2 male, 2 female members in the family. The family contains 2 married couples. C and A are related to each other by blood. A is related to B the same way D is related to C. If C is the father of A, how is D related to B?
C and A are related to each other by blood. There are 2 married couples in the family. Therefore, the other 2 must be spouses of these 2 persons.
C is the father of A. A is related to B the same way D is related to C. Therefore, A must be the husband of B and D must be the husband of C. As we can see, D must be the son-in-law of B. Therefore, option A is the right answer.
If 12 & 27 = 324 and 41 ! 73 = 114, then what is the value of 35 ! 16 & 18?
35 ! 16 & 18 = 35 + 16*18 = 323
Hence, option C is the right answer.
Which of the following Venn diagrams captures the relationship between predator, prey, goat, tiger, frog?
Some animals are both predator and prey. Frog eats insects and snakes eat frog. Therefore, frog is both a predator and prey.
Goat is a prey. Goats are herbivores and hence, they can be purely termed as preys. Tiger is an apex predator.
Therefore, the Venn diagram must contain 2 large intersecting circles and 3 small circles, one in each of the regions formed by the intersecting circles. Only option C satisfies this condition. Hence, option C is the right answer.
In the following diagram, each geometric shape represents a movie.
The number of people who have watched exactly 3 movies is
The region common to 3 shapes will give us the number of people who have watched exactly 3 movies.
From the diagram, the number of people who have watched exactly 3 movies is 8+2+13 = 23. Hence, option A is the right answer.

13 + 8 = 21
Squares of these numbers:
Ganesh walks 20 m towards the East. Then, he walks 3 m towards the south. He takes a turn and walks 4 m towards the East. Finally, he walks 10 m towards the North and comes to a halt. How far is Ganesh from his starting point?
The given statements can be expressed diagrammatically as follows:
Total distance travelled towards the East = 20 + 420+4 = 2424 m.
Total distance travelled towards the North = -3 + 10−3+10 = 77 m.
Distance from the starting point can be found using the Pythagoras theorem.
5 persons A, B, C, D and E live on 5 different floors of a building. The floors are numbered from 1 to 5, 1 being the topmost floor and 5 being the bottom most floor. A lives on an odd numbered floor above D. D has more persons living above him than below him. D lives on an even numbered floor. C lives on an odd numbered floor above D but below A. E lives on a floor above B. Who lives on floor 2?
1 is the topmost floor and 5 is the bottom-most floor. A lives on an odd numbered floor above D. Therefore, A must be living on floor 1 or 3. D has more persons living above him than below him. Therefore, D must be living on floor 4 or 5. D lives on an even numbered floor. Therefore, D must be living on floor 4. C lives on an odd numbered floor above D but below A. Therefore, A must be living on floor 1 and C must be living on floor 3. E lives on a floor above B. Therefore, B must be living on floor 5 and E must be living on floor 2.
The final arrangement is as follows:
1 - A
2 - E
3 - C
4 - D
5 - B
As we can see, E lives on the second floor. Therefore, option B is the right answer.
A machine codes DATE as 400 and TIME as 11700. The code for a 3 lettered word is 100. Which of the following cannot be the word?
DATE is coded as 400.
DATE - 4*1*20*5 - 400
TIME - 20*9*13*5 - 11700
Let us evaluate the options one by one.
DAY - 4*1*25 - 100
TEA - 20*5*1 - 100
EAT - 5*1*20 - 100
BET - 2*5*20 - 200
Therefore, option D is the right answer.
