A) Tuesday | B) Wednesday |

C) Monday | D) Saturday |

Explanation:

16th July, 1776 = (1775 years + Period from 1st Jan, 1776 to 16th July, 1776)

**Counting of odd days :**

1600 years have 0 odd day.

100 years have 5 odd days.

75 years = (18 leap years + 57 ordinary years) = [(18 x 2) + (57 x 1)] = 93 (13 weeks + 2 days) = 2 odd days

1775 years have (0 + 5 + 2) odd days = 7 odd days = 0 odd day.

Jan Feb Mar Apr May Jun Jul

31 + 29 + 31 + 30 + 31 + 30 + 16 = 198 days= (28 weeks + 2 days)

Total number of odd days = (0 + 2) = 2.

Required day was 'Tuesday'.

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.
