SAMPLE Q1. Ram moves 4 metres. in south direction then he moves 3 metres. in east direction. How far is he from the starting point?

a) 5 metres

b) 1 metre

c) 3 metres

d) 4 metres

Solution: This is a very basic mathematical question of standard 8th which can be solved by using Pythagoras Theorem. In the question it is given that from a certain position Ram is moving 4m towards south direction. And from there he is moving 3m towards east direction. We need to find the shortest distance between the initial position, from where he started moving, and his final position, where he reached after covering 3m towards east.

Sample Q2. Find the number of Trout in the tank!

Trout are bred in a tank as fish for restaurants. Twenty trout are caught and each is tagged through the tail then released back into the tank. A week later, thirty trout are caught and it is found that two of them have a tail tag.

Based on this evidence alone, what estimate can be made of the total number of trout in the tank ?

1) 100
2) 300
3) 600
4) 1200

Ans: Out of thirty trouts randomly picked, two are found to be having the tail tag. Going by the probability (2/30), the next 30 trouts caught would have 2 with tags and so on. To accomodate 20 tagged trouts the total number of trouts in the tank could be 30*10 or 300. [Linear extrapolation]. Option 2.

 

Sample Q3. Linguist Set theory question!

 A gathering of 50 linguists discovered that 4 knew Kannada, Telugu and Tamil, 7 knew only Telugu and Tamil, 5 knew only Kannada and Tamil, 6 knew only Telugu and Kannada. If the number of linguists who knew Tamil is 24 and those who knew Kannada is also 24, how many linguists knew only Telugu?

A) 9

B) 10

C) 11

D) 8

Ans:

We can attempt the set- based question step by step as shown below:

PSA_LEVEL-UP_QNR6

The ‘x’ in Step 3 can be calculated as:

50 – ( 7 + 8 +4 +5 +6 +9) = 11. Option C.
