All figures have perpendicular lines

Ans 30:

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.

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
