Q. If in a certain code, ‘ABCD’ is written as 24 and ‘EFGH’ is written as 1680, then how is ‘IJKL’ written in that code?
a) 11880
b) 11240
c) 7920
d) 5940
Correct answer: a) 11880
Question from UPSC Prelims 2024 CSAT
Explanation :
To determine how “IJKL” is encoded, let’s analyze the given examples:
1. ABCD:
A = 1, B = 2, C = 3, D = 4
Product: 1 x 2 x 3 x 4 = 24
2. EFGH:
E = 5, F = 6, G = 7, H = 8
Product: 5 x 6 x 7 x 8 = 1680
The pattern involves taking the numerical value of each letter (A=1, B=2, …, Z=26) and multiplying them together.
3. IJKL:
I = 9, J = 10, K = 11, L = 12
Product: 9 x 10 x 11 x 12 = 11880
Answer: a) 11880
