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)

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 )

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

Ans 19:

ANS 33 is correct

Ans 20:

Class : Class 6
How is the answer B?

Ans 21:

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 22:

Class : Class 7
it should be C

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.

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 5:

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

Ans 6:

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

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

Ans 12:

Class : Class 5

Ans 13:

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 14:

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

Class : Class 6
yes

Ans 23:

how

Ans 24:

D cannot be the answer at all.

Ans 25:

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