Question

In a code language, the number 21 is written as 231 and the number 53 is written as 583. How will the number 45 be written in that language?

1. 20
2. 495
3. 54
4. 465

Answer 1

Correct Answer - Option 2 : 495

The logic is:

21 → 2(2 + 1)1 = 231

53 → 5(5 + 3)3 = 583

Similarly,

45 → 4(4 + 5)5 = 495

Hence, ‘495’ is the correct answer.
