It is B since GH is not perpendicular by the smallest of angles. EF is perpendicular since if you look at the triangles or 5-sided shapes that are made when lines AB and EF come through a square with an angle not equal to 45 degrees, the sizes are the same. This shows that AB and EF are a pair of perpendicular lines.

D is the answer to this question because all the lines are perpendicular and in the 3rd one the bottom lines are perpendicular

Ans 3:

Class : Class 8
All 4 figure has perpendicular line along perimeter

Ans 4:

Class : Class 7
Something is wrong here. We have to confirm about it.

Ans 5:

Class : Class 5
it is d

Angles consideration is confusing ....sometime inner and sometime outer angle is consider ....actually SINGLE LINE FIGURE SHOULD BE GIVEN

Ans 20:

Class : Class 8

Ans 21:

Class : Class 6
how

Ans 22:

Class : Class 6
All figures have perpendicular lines

Ans 23:

Class : Class 7
It should be C as it is written that we have to find the perpendicular line for each figure, so there are three figures with perpendicular line but if we consider how many perpendicular lines are there in this picture then it should be 4. This answer is absolutely wrong.

Ans 24:

Class : Class 5
yes

Mrs Sharma wrote a 2-digit number on the blackboard. Three students Lalit, Vinay and Prashant said the following statements about that number.
Lalit : "It is a 2-digit number but not the least".
Vinay : "It is the predecessor of least 3-digit number".
Prashant : "It is having three different digits".
If only two of the three students said the truth, who is definitely lying?

A Lalit
B Vinay
C Prashant
D Both (A) and (B)

There are four equations P Q R=75; Q R S=90; P R S=100; Q S P=80Add them up all. You will get 3P 3Q 3R 3S=345. This means P Q R S=115We can replace the value of P Q R=75 in the above to get the value of S which would be 40. From the second equation, we can get the total value of Q R 40=90 as 50
