# Aptitude and Reasoning Questions

A) 11440 | B) 11998 |

C) 12240 | D) 12880 |

Explanation:

LCM of (80, 85, 90) can be found by prime factorizing them.

80 → 2 × 2 × 2 × 2 × 5

85 → 17 × 5

90 → 2 × 3 × 3 × 5

L.C.M of (80,85,90) = 2 × 2 x 2 × 2 × 3 × 3 × 5 × 17

= 16 x 9 x 85

= 144 x 85

= 12240

**L.C.M of (80,85,90) = 12240.**

A) Sister | B) Mother |

C) Grand Mother | D) Sister-in-law |

Explanation:

From drawing the relationships given above,

Sana is **Grand mother** of Sony.

A) 9 | B) 12 |

C) 18 | D) 24 |

Explanation:

From the given data,

P = 140

But it is given that,

**40% of Q + Q = 140 = P**

=> Q + [40Q/100] = 140

=> [100Q + 40Q]/100 = 140

=> 140Q = 140 x 100

=> Q = 100

Now,

**3/25 of Q **

= (3/25) x 100

= 3 x 4

= 12

Required** 3/25 of Q = 12.**

A) General reasoning | B) Perceptual speed |

C) Verbal comprehension | D) All of the above |

Explanation:

Aptitude tests measures an individual's level of competency to perform a certain type of task and their mental and physical potentials in dealing different situations. These tests include General reasoning, Verbal comprehension, Perceptual speed and numerical operations.

A) 196 | B) 148 |

C) 132 | D) 112 |

Explanation:

16 : 56 :: 32 : ?

Let the required number be **'n'**

The given numbers follow a logic that,

16/56 = 2/7

=> 32/n = 2/7

=> 32 x 7/2 = n

=> n = 112.

Hence, **16 : 56 :: 32 : 112.**

A) 11 and 4 | B) 3 and 11 |

C) 11 and 33 | D) 40 and 4 |

Explanation:

Let the smaller number be 'm'

Then, from the given data, the larger number is '3m'

Given that m + 3m = 44

=> 4m = 44

m = 44/4 = 11

=> m = 11

=> 3m = 3 x 11 = 33

Hence, the two numbers are 11 and 33.

A) Non-Concurrent forces | B) Coplanar forces |

C) Coplanar and concurrent forces | D) Any type of forces |

Explanation:

The Lami's theorem states that " If three forces coplanar and concurrent forces acting on a particle keep it in equilibrium, then each force is proportional to the sine of the angle between the other two and the constant of proportionality is the same." This theorem is derived from the Sine rule of triangles.
