Verification of Truth/ Lie of Statements - 2 | CSAT Preparation - UPSC PDF Download

The logic folllows here is:

I. Red is green, green is blue.

The codes in tabular form:

→ The colour of the sky is blue but here Green is Blue and no information for Blue is given. Thus, the statement is not sufficient to answer.

II. Blue is pink, pink is red.  

→ The colour of the sky is blue but here Blue is Pink. So, the colour of the sky is Pink. Thus, the statement is sufficient to answer.

Hence, the correct answer is "II alone is sufficient while I alone is not sufficient".

As per the given information:

Statement I: Vinod’s flat is located on an odd-numbered floor in a four-floored apartment, but he is not on the first floor.

Here, it is clear that Vinod is lived on 3rd floor 

Statement II: Guru’s flat is on the second floor.

Here, it is not clear which Vinod lived on which floor.

The logic followed here is:

In Statement I, it is given that X secured a rank higher than Q and Y but X is not the topper. However, it doesn't specify who secured the first rank.

In Statement II, it is given that P did not secure the first rank. However, it doesn't specify who secured the first rank.

Combining both statements, we know that X is not the topper and P is not the topper. it is given that X secured a rank higher than Q and Y.

By combining both statements we get Z as secured first rank.

Therefore, Both Statement I and Statement II together are necessary to answer the question.

The logic follows here is,

7461 is coded as 135:

​→ 74 + 61 = 135

Similarly,

6893 will be coded as:

​​→ 68 + 93 = 161 

Hence, the correct answer is "161".

The logic follows here is:

EARTH be written as QPMZS

Similarly,

HEART will be written as:

Hence, the correct answer is "SQPMZ".
