Ans 12:

Riddhiraj Saha from St. Xeviers Institution , Panihati, Kolkata
Class : Class 8

Ans 13:

Pratham Dave from GNS, Bangalore
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 14:

Rayna Agarwal from St. Xaviers High School, Gurgaon
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 15:

Shamvabi Samanta from Gitanjali Primary School,ICSE, Hyderabad
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.

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
