Question 1 |

In an equilateral triangle PQR, side PQ is divided into four equal parts, side QR is divided into six equal parts and side PR is divided into eight equals parts. The length of each subdivided part in cm is an integer. The minimum area of the triangle PQR possible, in cm^2, is

18 | |

24 | |

48 \sqrt{3}
| |

144 \sqrt{3} |

Question 1 Explanation:

For \left(\frac{a}{4}, \frac{a}{6}, \frac{a}{8}\right) to be integer, a must be LCM of 4, 6 and 8. So a = 24

\text { Area }=\frac{\sqrt{3}}{4} a^{2}=\frac{\sqrt{3}}{4} \times 24^{2}=144 \sqrt{3}

Question 2 |

In the figure shown above, PQRS is a square. The shaded portion is formed by the intersection of sectors of circles with radius equal to the side of the square and centers at S and Q.

The probability that any point picked randomly within the square falls in the shaded area is __________

4-\frac{\pi}{2} | |

\frac{1}{2} | |

\frac{\pi}{2}-1 | |

\frac{\pi}{4} |

Question 2 Explanation:

\begin{aligned} \text { Probability } &=\frac{f A}{T A} \\ f A &=\left(\frac{\pi r^{2}}{4}-\frac{r^{2}}{2}\right) \times 2 \\ \frac{f A}{T A} &=\frac{\left(\frac{\pi r^{2}}{4}-\frac{r^{2}}{2}\right) \times 2}{r^{2}}=\left(\frac{\pi}{2}-1\right) \end{aligned}

Question 4 |

The author said, "Musicians rehearse before their concerts. Actors rehearse their roles before the opening of a new play. On the other hand, I find it strange that many public speakers think they can just walk onto the stage and start speaking. In my opinion, it is no less important for public speaker to rehearse their talks."

Based on the above passage., which one of the following is TRUE?

Based on the above passage., which one of the following is TRUE?

The author is of the opinion that rehearsing is important for musicians, actors and public speakers | |

The author is of the opinion that rehearsing is less important for public speakers than for musicians and actors | |

The author is of the opinion that rehearsing is more important only for musicians than public speakers | |

The author is of the opinion that rehearsal is more important for actors than musicians |

Question 4 Explanation:

The last sentence of the passage decides the answer with the key words "No Less
Important".

Question 5 |

On a planar field, you travelled 3 units East from a point O. Next you travelled 4 units South to arrive at point P. Then you travelled from P in the North-East direction such that you arrive at a point that is 6 units East of point O. Next, you travelled in the North-West direction, so that you arrive at point Q that is 8 units North of point P.

The distance of point Q to point O, in the same units, should be _____________

The distance of point Q to point O, in the same units, should be _____________

Question 5 Explanation:

O Q=\sqrt{3^{2}+4^{2}}=5

Question 6 |

Four persons P, Q, R and S are to be seated in a row. R should not be seated at the second position from the left end of the row. The number of distinct seating arrangements possible is:

9 | |

18 | |

24 |

Question 6 Explanation:

Number of arrangements =3 \times 3 !=18

Question 7 |

\oplus and \odot are two operators on numbers p and q such that p \odot q=p-q, and p \oplus q=p \times q

Then, (9 \odot(6 \oplus 7)) \odot(7 \oplus(6 \odot 5))=

Then, (9 \odot(6 \oplus 7)) \odot(7 \oplus(6 \odot 5))=

40 | |

-26 | |

-33 | |

-40 |

Question 7 Explanation:

\begin{aligned} [9-(6 \times 7)]-[7 \times 1] &=-33-7 \\ &=-40 \end{aligned}

Question 8 |

Two identical cube shaped dice each with faces numbered 1 to 6 are rolled simultaneously. The probability that an even number is rolled out on each dice is:

\frac{1}{36} | |

\frac{1}{12} | |

\frac{1}{8} | |

\frac{1}{4} |

Question 8 Explanation:

Probability of getting even number on a dice=\frac{3}{6}=\frac{1}{2}

\thereforeTwo dice are rolled simultaneously,

Hence required probability =\frac{1}{2} \times \frac{1}{2}=\frac{1}{4}

\thereforeTwo dice are rolled simultaneously,

Hence required probability =\frac{1}{2} \times \frac{1}{2}=\frac{1}{4}
