In a certain code language, ‘YOU’ is written as ‘7878’ and ‘GO’ is written as ‘108’. How will ‘SIT’ be written in that language?
3423
3419
3414
3420
Correct answer
3423
Why this answer is correct
The logic followed here is:
Logic: (Product of the place value of all numbers) + 3 = Code of the word.
'YOU’ is written as ‘7878'
⇒ (25 × 15 × 21) + 3
⇒ 7875 + 3 = 7875.
'GO’ is written as ‘108'
⇒ (7 × 15) + 3
⇒ 105 + 3 = 108.
Similarly, for 'SIT'
⇒ (19 × 9 × 20) + 3
⇒ 3420 + 3 = 3423.
So, 'SIT' will be written as '3423'.
Hence, the correct answer is "Option 1".
