Correct Answer: 5

Solution : According to the dice rule, if two or three positions of the same dice are given with two common faces but in different orientations then out of those two common faces the faces that are not common are opposite to each other.

Therefore, the opposite face of the 2 is 5. Hence, the fourth option is correct.

Correct Answer: (2)

Solution : The correct choice is the second option. 

The reason for the error is the subject-verb agreement. The subject "behaviour of young boys" is singular, so the verb should also be singular, which is "is" instead of "are".

Therefore, the correct sentence is: The behaviour of young boys is the subject of comment the world over.

Correct Answer: O/C

Solution : Given:
$\frac{W}{S}, \frac{U}{O}, \frac{S}{K}, \frac{Q}{G}$

Here, each term has two parts nominator and denominator. In the given series subtract 2 from the nominator and subtract 4 from the denominator to get the missing term.
W – 2 = U, U – 2 = S, S – 2 = Q, Q – 2 = O;
S – 4 = O, O – 4 = K, K – 4 = G, G – 4 = C.

So, the required missing term is O/C. Hence, the fourth option is correct.

Correct Answer: $66 \frac{2}{3} \%$

Solution : Given: 30% of Ravi’s income = 40% of Suresh’s income
⇒ $\frac{\text{Ravi's income}}{\text{Suresh's income}}=\frac{40}{30}$
50% of Ravi's income = $\frac{50}{100}\times40= 20$
Required percentage = $\frac{\text{50% of Ravi's income}}{\text{suresh income}}\times100$
= $\frac{20}{30}\times100$
= $66 \frac{2}{3}\%$
Hence, the correct answer is $66 \frac{2}{3} \%$.
