Q1. Ramu & sangeetha went for biological analysis to a island which is 34km from their place. They travelled in a boat which went at a speed of 2m/s. when they are in half a distance in the boat sangeetha note there are 7 leg & 8 leg octopuses under the water. Ramu counted the total number of legs of octopuses and got 54. Sangeetha instantly said I know how many 7 leged octopuses are there under the water. They both reached the island after 20 min they left . How many seven leged octopuses does sangeetha calculate?

1. 4

2. 5
3. 6
4. 7

ANS: Total number of legs of both 7 & 8 leged octo bus

Find number of 7 leged octopuses

4(7 leged octobus) + X = 54.

5(7 leged octobus) + X = 54. Similarly do for all. The x you get should be exactly divisible by 8. Only one answer will satisfy the condition.

Note : you may find lot of nonsense stuff to test verbal ability. Just take required data alone. From the next question on wards I post necessary data only.

Q2. Total number of wheels of bicycles & 4 wheeled vehicles is 38. How many bicycles are there? ( This question has more than 6 lines to test your verbal ability)

ANS: similar to above.

Choices from answer(2 wheelers) + X = 38. X should be exactly divisible by 4

ANS: White

Q5. There are 14 spots. Each spot has 8 seats. 28 people seated in all the spots. No similar number people sat in any spot. How many spots left with no people at all

ANS: 1+2+3+4+5+6+7 = 28. So remaining 7 spots has no people at all

Q6. Can A has milk. Can b had water. A spoon of milk from can A is added to Can B. Then from the mixture same amount is taken from Can B and added to Can A.

ANS: Can A contains less item than item in Can B

Q7. There is a plane contains 32 points. All the 32 points have equal distance from point x.

Which of the following is true

A:All the 32 points lie in circle.

B:The distance from x to all 32 points is less then the distance between each other

ANS: A only

Q8. Horse ran at speed of 34 kmph. Pony started after 2 hours. Horse ran for 4 hours. What is the speed of pony?

ANS: (34*4)/(4+2)
