I attempt 30 uestions which was correct.You can get through if you prepared with previous papers and having a little presence of mind. I m giving u the questions with solution of some of them.
1. (1/2) of a number is 3 more than the (1/6) of the same number?
a) 6
b)7
c)8
d)9
Solution:
Let the number be x,
((1/2)*x)=3+(1/6)*x,
Then solve x
2. There are two water tanks A and B, A is much smaller than B. While water fills at the rate of 1 liter every hour in A, it gets filled up like, 10, 20, 40, 80, 160 in tank B. (At the end of first hour, B has 10 liters, second hour it has 20 liters and so on). If tank B is 1/32 filled of the 21 hours, what is total duration of hours required to fill it completely?
a) 26
B)25
c)5
d)27
Solution: for every hour water in tank in B is doubled, Let the duration to fill the tank B is x hours. x/32 part of water in tank of B is filled in 21 hours, Next hour it is doubled so,
2*(x/32) part i.e (x/16) part is filled in 22 hours, Similarly (x/8)th part in 23 hours,(x/4)th part is filled in 24 hours, (x/2)th part is filled in 25 hours, (x)th part is filled in 26 hours So answer is 26 hours.
3. 6 persons standing in queue with different age group, after two years their average age will be 43 and seventh person joined with them. Hence the current average age has become 45. Find the age of seventh person?
a) 43
b) 69
c) 52
d) 31
Solution:
Total age of 6 persons is x hours, after two years total age of 6 persons is x+12 Average age of 6 persons is after two years is 43 So (x+12)/6=43,then solve x,
After 7th person is added then (x+7th person age)/7=45 So we will get 7th person age easily
4.In the reading room of a library, there are 23 reading spots. Each reading spot consists of a round table with 9 chairs placed around it. There are some readers such that in each occupied reading spot there are different numbers of readers. If in all there are 36 readers, how many reading spots do not have even a single reader?
a) 8
b) none
c) 16
d) 15
Solution: 23 reading spots, Each reading spot consists of 9 chairs placed around it so There are some readers such that in each occupied reading spot there are different numbers of readers. For each table different no of persons are sat,so for first table 1 person is sit,2nd table 2 persons are sit 36
readers means(1+2+3+4+5+6+7+8 so 8 tables are filled so 23-8=15 reading spots does not have single reader.
5. A man jogs at 6 mph over a certain journey and walks over the same route at 4 mph. What is his average speed for the journey?
a) 2.4 mph
b) 4.8 mph

d) 5 mph
Solution: Average speed=(2*x*y)/(x+y)
6. Susan made a block with small cubes of 8 cubic cm volume to make a block ,3 small cubes long, 9 small cubes wide and 5 small cubes deep. She realizes that she has used more small cubes than she really needed. She realized that she could have glued a fewer number of cubes together to lock like a block with same dimensions, if it were made hollow. What is the minimum number of cubes that she needs to make the block?
a) 114
b) 135
c) 21
d) 71
Solution: ,((3*9*5))-((3-2)*(9-2)*(5-2)) so answer is 114.
7. ((4x+3y)+(5x+9y))/(5x+5y) = ? as (x/2y) = 2
a)8
b) none
c)16
d)15
Solution: substitute x=4y
8. A girl has to make pizza with different toppings. There are 8 different toppings. In how many ways can she make pizzas with 2 different toppings?
a) 16

9. A toy train produces 10 different sounds when it moves around a circular toy track of radius 5 m at 10 m per min. However, the toy train is defective and it now produces only 2 different tunes at random. What are the odds that the train produces for consecutive music tones of the same type?
a) 1 in 16
B) 1 in 4
c) 1 in 8
d) 1 in 32
Solution: Initially it produces 10 sounds and the defect came and now it produces only 2 different sounds and consecutively so there are totally 2 sounds and we have to select on sound and the probability is ½ and it produces the same sound concecutively for 2 times so the probability becomes ½*1/2 ie ¼
10. A triangle is made from a rope. The sides of the triangle are 25 cm, 11 cm and 31 cm. What will be the area of the square made from the same rope?
a) 280.5625

c) 280.125
d) 240
Solution: add all sides 25+11+31 to get rope length rope length =67,rope is made in to as square So side of square is 67/4=16.75 and so area is 16.75*16.75=280.5625
