Ans 3:

OISHIK KUNDU from Delhi Public school North kolkata, baranagar
Class : Class 4
Let’s see what pattern is being followed by the numbers in the above grid. Let’s take the first column – 7, 81, 2 If we add 1st and 3rd number = 7 2 = 9 And if we multiply 9 by 9 itself = 9 x 9 = 81. 81 is the 2nd number in the first column. Let’s see if the numbers in second column follow the same pattern. 9, 169, 4 We add 1st and 3rd number = 9 4 = 13 We multiply 13 by 13 itself = 13 x 13 = 169. 169 is the 2nd number in the second column. That means the numbers of third column will follow the same pattern. 11, ?, 6 We add 1st and 3rd number = 11 6 = 17 We multiply 17 by 17 itself = 17 x 17 = 289. 289 will be the missing number in the third column. So, the correct answer is Option D.

Gauri Singh from St Johns School Marhauli, Varanasi
Class : Class 8
option C is the answer as when you fold each of the other figures (opt. a, b, d), you will get the same cuboid as asked in the question. But in the third option, when you fold the figure along the lines, you will get a cuboid whose one face is missing..... So, this is the explanation :)
