Solution
The correct option is B 19 : 361 : 342
The second number is the square of the first number and the third number is obtained by subtracting first
number from the second number.
(11)2=121,and121−11=110(11)2=121,and121−11=110
(15)2=225,and225−15=210(15)2=225,and225−15=210
Similarly, (19)2=361,and361−19=342(19)2=361,and361−19=342
So, the answer is (b).
The second number is the square of the first number and the third number is obtained by subtracting first

(11)2=121,and121−11=110(11)2=121,and121−11=110
(15)2=225,and225−15=210(15)2=225,and225−15=210
Similarly, (19)2=361,and361−19=342(19)2=361,and361−19=342
So, the answer is (b).
