Question of The Day30-09-2019

What will be the wrong number in the given number series, given that the other numbers follows a certain pattern?

17.11, 19.22, 21.44, 23.66, 25.88, 27.10, 30.32

Answer

Correct Answer : c ) 27.10

Explanation :

Consider the given series

17.11, 19.22, 21.44, 23.66, 25.88, 27.10, 30.32            

The logic for the above series can be explained as

17.11 = 17 + 0.11

19.22 = 17 + 2 + 0.11*2

21.44 = 17 + 4 + 0.11*4

23.66 = 17 + 6 + 0.11*6

25.88 = 17 + 8 + 0.11*8

17 + 10 + 0.11*10 = 28.10 ≠ 27.10

30.32 = 17 + 12 + 0.11*12

Thus, 27.10 is the wrong term in the given series

Hence, (C) is the correct answer.

Question of The Day21-07-2019

What will be the total surface area of the symmetrical pyramid having a square base with an area of 576 \( m^2\) and height 5 m?

Answer

Correct Answer : a )    A) \({1200 m^2}\)

Explanation :

Given:

Height (H) = 5 m

Area of square base =\(576 m^2\)

So, Side of the square, a = \( \sqrt{576} \) = 24 m

Now,

 

The lateral height of the triangle, L

L = \(\sqrt{H^2+{(\frac{a}{2}})^2}\)

L = \(\sqrt{5^2+{(\frac{24}{2}})^2}\)

L = 13m

There are 4 symmetrical triangles in the pyramid so, the total surface area of the pyramid is

= 4 x (area of triangles) + area of base

= \(4*(\frac{1}{2}*base*height)+576\)

=\(4*(\frac{1}{2}*24*13)+576\)

= 624 + 576

\(1200 m^2\)

Hence, (a) is the correct answer.
