Direction (): Match the column I and II based on the given questions

If height of X is greater than height of Y.

(i) Only A, either B or C
(ii) Only A
(iii) Only A

(i) Either B or C
(ii) Only A
(iii) Only A, either B or C

(i) Only B
(ii) Only A
(iii) Only A

(i) Only C
(ii) Only B
(iii) Only B

None of these

Let height of X be hx and height of Y be hY

We have to find hx > hY

When we take radius of Y = 7 m

We get height of Y = 12 m

And when we take radius of Y = 14 m

We get height of Y = 3 m

Now, 1/3 × 22/7 × r² h + 2/3 ×22/7× r³ = 1232

r² (h + 2r) = 168 ×7

now when take r = 7 m for X

then hx = 10 m

and when we take r = 14 m for X we get hx in negative which not possible

Now for satisfied hx > hY , height of Y should be 3 m

So, answer should be

(i) Either B or C

(ii) Only A

(iii) Only A, either B or C
