All except White are colours of the' rainbow.

Paper is folding from upper part to lower part and it will make a triangle in lower side area. Please take a transparent paper and draw the similar figure and fold it.

A man walks 30 meters towards South, then turning to his right, he walks 30 meters, then turning to his left, he walks 20 meters, again turning to his left, he walks 30 meters. The figure are given below -

50 meters far is he from his starting point.

Hence, "50 meters" is the correct answer.

 5 / (3 + √8)  x  ( (3 - √8) /  (3 - √8)

=  5 ( 3 - √8)/(3^{2 -} 8 ⁾

= 5 ( 3 - √8 ) / 9 - 8  = 15 - 5√8 

So option C is correct. 

As we know that the angles are supplementary so sum of angles will be 180 degree.
Let us assume that the ratio factor is r.
According to question,
Angles are supplementary and have a ratio of 1:4.
r + 4r = 180
⇒ 5r = 180
⇒ r = 180/5
⇒ r = 36

2D definition - A two-dimensional (2D) object is an object that only has two dimensions, such as a length and a width, and no thickness or height.  Since the plane figure has no thickness or height so it will be 2d figure.

The average of the last two numbers

Hence, Option A is correct.

One side by car = 5 – 4 = 1 hour
So the answer = 1 × 2 = 2 hours
Hence, Option B is correct.

Noise level in dB = 10Log₁₀ (Noise in watts)

10 dB = 10Log₁₀ (Noise in watts)

Noise in watts for 10 dB = 10¹ = 10 Watts …(1)

1dB = 10 Log₁₀ (Noise in watts)

Noise in watts for 1 dB = 10^0.1 = 1.26….(2)

P₁/P₂ = 10/1.26 = 7.94 W
