Description
Consider a set of digits that can be used to add up various sums from 1 to 120. What would be the minimum number of digits needed to achieve this?
1. Analytical thinking : You need to demonstrate the ability to analyze and break down a complex problem into smaller, more manageable parts.
2. Mathematical skills : The ability to understand and manipulate numbers to find a solution is crucial.
3. Logical reasoning : A logical approach is necessary to deduce the least number of digits required.
4. Attention to detail : Careful consideration of the range of sums is necessary to avoid miscalculations.
1. Problem-solving assessment : The interviewer wants to assess your problem-solving capabilities.
2. Understanding of numerical concepts : They are interested in verifying your grasp of numerical and mathematical concepts.
3. Evaluating logical reasoning : The question is an opportunity to showcase your reasoning ability in approaching mathematical challenges.
4. Checking analytical abilities : Your analytical skills are tested to see how you dissect a problem and work toward a solution.
1. Consider binary representation : Think about how numbers can be represented in binary to understand the building blocks required for sums.
2. Think about the powers of 2 : Powers of 2 play a crucial role in constructing other numbers through summation.
3. Remember the uniqueness of each sum : Consider that each sum from 1 to 120 must be uniquely obtainable using the chosen digits.
