Question

Which choice is more than 11 but less than 12?

Answer 1

Let
x--------> the number

we know that
11²=121
12²=144

then
x² must be greater than 121  and less than 144

case a) √115
if x=√115
then
 x²=115-------> is not greater than 121

case b) √121 
if x=√121
then
 x²=121-------> is not greater than 121

case c) √136
if x=√136
then
 x²=136-------> is greater than 121 and is less than 144------> is ok

case d) √150
if x=√150
then
 x²=150------> is not less than 144

therefore

the answer is
√136
