All of them were made of glass. So if P was left as it is without painting wouldn't it be transparent??

Ans 5:

Falguni from Navkis, Bangalore
Class : Class 7
Even C is correct. In the workbook solution it’s given that slideR is supposed to be opaque

Ans 6:

Ashwak from Cambridge, Jalandhar
Class : Class 9
Sorry for the typo answer C is incorrect

Ans 7:

Shaurya Rai from Vibgyor High Balewadi, Pune
Class : Class 6
Option A can also be a correct answer because the transparency of the glass is not mentioned. It can be translucent or transparent as well.

Ans 8:

Shuvangi Das from Vivekananda mission school, haldia
Class : Class 9
Bcoz when glass Q is painted with light blue we are still able to see the mark , that means its still translucent. When glass R is painted with black, we are not able to see as black is an opaque color. This what the logic meant for. So, option B is correct

Ans 9:

Aarush Goyal from D.A.V Pblic school, Sector 14, Faridabad

IT IS AND THE ANSWER IS B

Ans 10:

Arsh from Lahs, Gwalior
Class : Class 3
why!

Ans 11:

tanmay chaudhry from BAL BHAVAN PUBLIC SCHOOL, New Delhi
Class : Class 4
slide r is opaque and slide q is translusent

Ans 12:

Ashwak from Cambridge, Jalandhar
Class : Class 9
Falguni and Tanmay , the C option is correct as R is opaque but the question is through which slide can we see the X mark clearly or partially and we can't see through because as you said R is opaque . Answer D is not correct either because colour affects the transparency of the slide. Answer A is not correct because P is transparent not translucent. That leaves us with Option B which is correct as Q is translucent and the students can see the X partially through it . Hope this explanation helps you clear all your doubts about this question.💜💜💜Oh and by the way completely not related to the question who else is an army ( BTS fans ) ?
