Question

Ramesh bought a new lock with a 3-digit code. he asked one of his friends to join him to try to crack the code. his friend tried few combinations and with every combination ramesh was helping his friend with some hints. few of the combinations and hints is shown in the following image. what is the code for the lock?

(a) 432
(b) 336
(c) 672
(d) 288

Answer 1

The correct lock code is (c) 672, determined through a process of elimination using the hints provided with each incorrect guess.

Step-by-step explanation:

The correct answer is option (c) 672. To determine the lock code from the given combinations and hints, a process of elimination is used. Each hint provided by Ramesh eliminates certain digits or combinations of digits. For instance, if one of the digits in the friend's guess is correct and well placed and two digits are correct but placed in the wrong position, it informs us about which digits could be part of the code and their possible placements.

By comparing all the hints, one can determine which digits are correct and their proper sequence. For instance, if one of the digits in the friend's guess is correct and well placed and two digits are correct but placed in the wrong position, it informs us about which digits could be part of the code and their possible placements. By comparing all the hints, one can determine which digits are correct and their proper sequence. Analyzing the options given, we can deduce that option (c) 672 aligns with the hints provided and would therefore be the lock's correct 3-digit code.

Analyzing the options given, we can deduce that option (c) 672 aligns with the hints provided and would therefore be the lock's correct 3-digit code.
