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) 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

A) 22% | B) 33% |

C) 44% | D) 55% |

Explanation:

Let original length = x metres and original breadth = y metres.

Original area = xy sq.m

Increased length = $\frac{120}{100}$ and Increased breadth = $\frac{120}{100}$

New area = $\frac{120}{100}x*\frac{120}{100}y=\frac{36}{25}xy{m}^{2}$

The difference between the Original area and New area is:

$\frac{36}{25}xy-xy$

$\frac{11}{25}xy$ Increase % =$\left(\raisebox{1ex}{$\frac{11}{25}xy$}\!\left/ \!\raisebox{-1ex}{$xy$}\right.\right)*100$= 44%
