# 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
