Question : In a regiment, the ratio between the number of officers to soldiers was 3 : 31 before the battle. In a battle, 6 officers and 22 soldiers were killed. The ratio became 1 : 13. The number of officers in the regiment before the battle was:
Option 1: 31
Option 2: 38
Option 3: 21
Option 4: 28
Correct Answer: 21
Solution : Before the battle: Let the number of officers be $3x$. Let the number of soldiers be $31x$. After the battle: Let the number of officers be $3x-6$. Let the number of soldiers be $31x-22$. According to the given condition, $\frac{3x-6}{31x-22}=\frac{1}{13}$ $⇒39x-78=31x-22$ $⇒8x=56$ $\therefore x=7$ So,
Question : Directions: Three statements are followed by three conclusions numbered I, II, and III. You have to consider these statements to be true, even if they seem to be at variance with commonly known facts. Decide which of the given conclusions logically follows from the given statements. Statements: All peacocks are pigeons. Some pigeons are pink. Some pinks are birds. Conclusions: (I) Some pinks are peacocks. (II) Some birds are pigeons. (III) Some peacocks are birds.

Option 2: Either conclusion I or conclusion III follows
Option 3: Only conclusion II follows
Option 4: Only conclusion I follows
Correct Answer: None of the conclusion follow
Solution : According to the statements, the following Venn diagram can be drawn –
Let's analyse the conclusions – Conclusion I: Some pinks are peacocks – From, the above diagram it is evident that there is no direct relation between peacocks and pinks.

Question : Direction: N is more intelligent than M. M is not as intelligent as Y. X is more intelligent than Y but not as good as N. Who is the most intelligent of all?
Option 1: M
Option 2: Y
Option 3: N
Option 4: X

N is more intelligent than M → N > M
M is not as intelligent as Y → Y > M
X is more intelligent than Y but not as good as N → N > X > Y
So, from the above →
Question : Menu and Daya travel from point A to B, a distance of 105 km, at speeds of 10 km/hr and 25 km/hr, respectively. Daya reaches point B first and returns immediately and meets Menu at point C. Find the distance from point A to point C.
Option 1: 35 km
Option 2: 60 km
Option 3: 45 km
Option 4: 62 km
Correct Answer: 60 km
Solution : The distance of A and B = 105 km Let's assume that they meet at point C, and CB = $x$ Then AC = $(105 - x)$ Speed of Daya = 25 km/hr Speed of Menu = 10 km/hr Distance covered by Daya =
