Ans 4:

Class : Class 8
The answer is D only

Class : Class 5

Ans 6:

Class : Class 5
b is not the answer but d because in a symetry , both the sides should be opposite .

According to me the correct answer to this question is D] Because it has a line of symmetry from top to bottom

Ans 3:

Class : Class 5
D is the answer because it is straight but option B is not correct because over here it is slanting , and there is no such symmetry

Ans 4:

Class : Class 5
I say B is also a line of symmetry but the correct answer is D

Ans 5:

Class : Class 5
But B answer is also the correct answer

Ans 6:

Class : Class 5
But B has slanting line of symmetry.The line of symmetry doesn't means only to be strategy

Ans 7:

Class : Class 5
the answer to this question can also be b because option b also has a line of symmetry

Ans 8:

Class : Class 5
sorry

Ans 9:

Class : Class 5

Ans 10:

Class : Class 8
answer is not b because the lines on top of the letter are horizontal

option a is correct as angle pqs is epual to angle qsa +angle ast (alternate interior angle)=70 98=28+x x=98-28 x=70 ast+tsb=180(straight angle) 70+y=180 y=180-70 y=110

It's simple addition and subtraction. The total cost of both toys is 52.45+25.32=77.77 You gave him a hundred rupee note. So you gave him 22.23 rupees morethe actual prize which you would recieve as change. So the answer is 22.23 (100-77.77=22.23)

Ans is C..... Olympiad Trainer please give master answer or solution.

Ans 3:

Class : Class 8

Ans 4:

Class : Class 5
It is B because the point where EF and AB met it is the centre point of 4 squares making it correct. Guys it is easy but we must know the trick (btw some questions are wrong itself )

Ans 5:

Class : Class 5

Ans 6:

Class : Class 7
it should be C

Ans 7:

Class : Class 8
All transversal lines look perpendicular

Ans 8:

Class : Class 6
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.

Class : Class 6
WHOEVER HAS STUDIED IN GURRUZI 2024 WOULD KNOW THIS ANSWER BUT THE QUESTION ITSELF IS WRONG IT SHOULD BE WHICH ONE OF FOLLOWING IS (NOT) perpendicular to Ab

Wrong options SOF.!!!!!! Do you want us to fail

Class : Class 6
The answer is C] GH Because if we count the blocks in AB then, it's4 If we count the blocks in GH then, it's4 THIS S MY FORMULAE

ans 7 is right. perpendicular = 90 degree intersecting straight lines

Ans 33:

Class : Class 5
the answer is d as the line needs to be a proper slant and only i-j is properly slanted

It is c

Ans 2:

Class : Class 8

Ans 3:

Class : Class 8

Ans 4:

Class : Class 5
'c' = correct

Ans 5:

Class : Class 5
The answer should be C because in the first figure there are prependicular lines in the bottom in figure 2 there are prependicular lines all four sides near the arrows and in figure 3 there are prependicular lines at the bottom while there are no prependicular lines in figure 4 as they are all acute and obtuse angles so, the answer should be C not D.

Ans 6:

Class : Class 9
D cannot be the answer at all.

Class : Class 4

Ans 8:

Class : Class 5

Ans 9:

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

Ans 10:

Class : Class 5
it should be a. thats what my supery dupery expert dad said

Ans 11:

Class : Class 9
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 12:

Class : Class 9
All figures have perpendicular lines

Ans 13:

Class : Class 7
CONFUSING QUESTION

Ans 14:

Class : Class 7

Ans 15:

Class : Class 5
How

Ans 16:

Class : Class 5
A perpendicular line is 90 degrees, last one doesn't count as 90 degrees, so C

Ans 17:

Class : Class 6

Ans 18:

Class : Class 7
D is the answer to this question because all the lines are perpendicular and in the 3rd one the bottom lines are perpendicular

Ans 19:

Class : Class 6
yes

Ans 20:

Class : Class 9
But what about the curved arrow
