No, the correct answer is D. When written in decimal, the value of it comes out to be 0.2 and the rest are bigger than it. In fractions, as the denominator gets bigger, the number gets smaller.

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

Ans 2:

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 ) ?

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 4:

Class : Class 9
Sorry for the typo answer C is incorrect

Ans 5:

Class : Class 4
slide r is opaque and slide q is translusent

Ans 6:

Class : Class 6

Ans 7:

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

Ans 8:

Class : Class 9

Ans 9:

Class : Class 3

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 12:

Class : Class 4
