121 = 112, 144 = 122, 169 = 132, 196 = 142, 225 = 152.

2.    (B)
5 x 11 = 55, 55 x 11 = 605, 605 x 11 = 6655, 6655 x 11 = 73205

3.  (D)
2025 = 452, 2116 = 462, 2304 = 482, 2401 = 492, 2500 = 502

4     (A)
The given series is : 13 – 1, 23 – 2, 33 – 3, 43 – 4, 53 – 5, 63 – 6,
So the missing term = 73 – 7 = 343 – 7 = 336 .
