Correct Answer: 31

Solution : Given:
I = 9 and SLIP = 56

Add the place value of the letters to get the required code –
Like, the place value of the letter I; I→9
Thus, I is coded as 9.
Place values of the letters of SLIP; S→19; L→12; I→9; P→16
SLIP→19 + 12 + 9 + 16 = 56
Thus, SLIP is coded as 56.
Similarly, follow the same pattern for FALL; F→6; A→1; L→12; L→12
FALL→6 + 1 + 12 + 12 = 31

Thus, the code for FALL is 31. Hence, the second option is correct.
