Correct Answer: 49
Solution :
Given:
PEN is coded as 9 and PAPER is coded as 25.
Square the number of letters in PEN, to get the required code –
The number of letters in PEN is 3, and 3
2
= 9
Thus, PEN is coded as 9.
And, PAPER is coded as 25 –
The number of letters in PAPER is 5, and 5
2
= 25
Thus, PAPER is coded as 25.
Similarly, follow the same pattern for CHAPTER –
The number of letters in CHAPTER is 7, and 7
2
= 49
Thus, CHAPTER is coded as 49. Hence, the second option is correct.
