# Bank PO Questions

A) 54 past 4 | B) (53 + 7/11) past 4 |

C) (54 + 8/11) past 4 | D) (54 + 6/11) past 4 |

Explanation:

4 o'clock, the hands of the watch are 20 min. spaces apart.

To be in opposite directions, they must be 30 min. spaces apart.

Minute hand will have to gain 50 min. spaces.

55 min. spaces are gained in 60 min

50 min. spaces are gained in $\frac{60}{55}\times 50$ min. or $54\frac{6}{11}$

Required time = $54\frac{6}{11}$ min. past 4.

A) 360 | B) 180 |

C) 90 | D) 60 |

Explanation:

Angle traced by the hour hand in 6 hours=(360/12)*6

A) 55% | B) 65% |

C) 75% | D) 85% |

Explanation:

Let original radius = R.

New radius = $\frac{50}{100}R$= $\frac{50}{100}R$

Original area =$\frac{R}{2}$ and new area = ${\mathrm{\pi R}}^{2}$

$\frac{3{\mathrm{\pi R}}^{2}}{4}*\frac{1}{{\mathrm{\pi R}}^{2}}*100$

Decrease in area = $\mathrm{\pi}{\left(\frac{\mathrm{R}}{2}\right)}^{2}=\frac{{\mathrm{\pi R}}^{2}}{4}$ = 75%

A) 2.875 | B) 3.875 |

C) 4.875 | D) 5.875 |

Explanation:

ANS: log_{5}512 = log512/log5 = $\frac{\mathrm{log}{2}^{9}}{\mathrm{log}\left(10/2\right)}$ =$\frac{9\mathrm{log}2}{\mathrm{log}10-\mathrm{log}2}$ =$\frac{9*0.3010}{1-0.3010}$ =2.709/0.699 =2709/699 =3.876

A) Diffraction of light | B) Dispersion of light |

C) Reflection of light | D) Refraction of light |

Explanation:

A clear cloudless day-time sky is blue because molecules in the air dissipate blue light from the sun more than they dissipate red light. When we look towards the sun at sunset, we see red and orange hues on the grounds because the blue light has been scattered out and away from the line of sight.

A) Supreme Court | B) Parliament |

C) Constitution | D) President |

A) 0.754 | B) 0.854 |

C) 0.954 | D) 0.654 |

Explanation:

log 27 = 1.431

log$\left({3}^{3}\right)$ = 1.431

3 log 3 = 1.431

log 3 = 0.477

log 9 = log(${3}^{2}$)= 2 log 3 = (2 x 0.477) = 0.954
