$$\eqalign{ & {\text{I}}.\sqrt {121} + \sqrt {12321} + \sqrt {1234321} = 1233 \cr & {\text{II}}.\sqrt {0.64} + \sqrt {64} + \sqrt {36} + \sqrt {0.36} > 15 \cr} $$

A. Only I

B. Only II

C. Neither I nor II

D. Both I and II

Answer: Option D

Solution (By Examveda Team)

$$\eqalign{ & {\text{I}}.\sqrt {121} + \sqrt {12321} + \sqrt {1234321} = 1233 \cr & 11 + 111 + 1111 = 1233 \cr & 1233 = 1233 \cr & {\text{II}}.\sqrt {0.64} + \sqrt {64} + \sqrt {36} + \sqrt {0.36} > 15 \cr & \frac{8}{{10}} + 8 + 6 + \frac{6}{{10}} > 15 \cr & 15.4 > 15 \cr & {\text{Hence statement II is also true}}{\text{.}} \cr} $$
