Bank Exams Questions

A) Congruent | B) Coplanar points |

C) Collinear points | D) None |

Explanation:

Points that lie on the same line are called Collinear points. And that points lie on the same plane are called Coplanar points.

A) Liquid to Solid | B) Gas to Solid |

C) Gas to Liquid | D) All the above |

Explanation:

Processes that require or give off heat will be limited to changes of state, known as phase changes, and changes in chemical constitution, or chemical reactions. Changes of state involve a solid melting, a liquid freezing, a liquid boiling or a gas condensing.

An exothermic process is one that gives off heat, which is transferred to the surroundings. An endothermic process is a reaction which heat has to be supplied to the system from the surroundings.

Here in all the given options, heat is taken away from them to change there phase.

Liquid to Solid --- Freezing

Gas to Liquid --- Condensation

Gas to Solid --- Deposition

are all examples of exothermic processes.

A) a vein | B) a lacteal |

C) an artery | D) a capillary |

Explanation:

A pulse can be detected most easily in Arteries as they are under much greater pressure than veins because they are carrying blood away from the heart which is the pumping machine to force blood to move to all of the body.

Every time the hear contracts, it can be felt in an artery where a surge of blood has just been forced.

A capillary is too small to feel a pulse and a lacteal is part of the lymphatic system found in the small intestine.

A) Condensation | B) Evaporation |

C) Sublimation | D) Freezing |

Explanation:

Sublimation is a process when a solid changes directly into gas instead changing into liquid first. Dry ice is an example of Sublimation process because it doesn't change into liquid CO2 and directly change into gaseous CO2 when heated.

Hence, **Dry ice is an example of Sublimation process. **

A) 25 | B) 26 |

C) 27 | D) 28 |

Explanation:

This can be easily simplified by Approximation process

Given **39.96% of 649.85 $\xf7$13.07 = 45.14 - ? **can be written as

40% of 650 $\xf7$13 = 45 - ?

$\frac{{\displaystyle \frac{40\mathrm{x}650}{100}}}{13}=45-?\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}?=45-20\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}\mathbf{?}\mathbf{}\mathbf{=}\mathbf{}\mathbf{25}\mathbf{.}$

Given A,B,C can complete a work in 15,20 and 30 respectively.

The total work is given by the LCM of 15, 20, 30 i.e, 60.

A's 1 day work = 60/15 = 4 units

B's 1 day work = 60/20 = 3 units

C's 1 day work = 60/30 = 2 units

(A + B + C) worked for 2 days = (4 + 3 + 2) 2 = 18 units

Let B + C worked for x days = (3 + 2) x = 5x units

C worked for 2 days = 2 x 2 = 4 units

Then, 18 + 5x + 4 = 60

22 + 5x = 60

5x = 38

x = 7.6

Therefore, total number of days taken to complete the work **= 2 + 7.6 + 2 = 11.6 = 11 3/5 days.**

A) Rs. 180 | B) Rs. 150 |

C) Rs. 120 | D) Rs. 240 |

Explanation:

Given 30% of 500

$\mathbf{=}\mathbf{}\frac{\mathbf{30}}{\mathbf{100}}\mathbf{}\mathbf{x}\mathbf{}\mathbf{500}\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}=30\mathrm{x}5\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}\mathbf{=}\mathbf{}\mathbf{150}$

Hence, **30% of Rs. 500 = Rs. 150.**
