Question
In a certain coding system, ‘matter occupies
anything’ is coded as ‘395’, ‘that occupies space’ is coded as ‘941’ and ‘that matter requires’ is coded as ‘348’. How is ‘space requires matter’ coded in the same coding system?Solution
After decoding the codes, we get: matter – 3, occupies – 9, anything – 5, that – 4, space – 1, requires – 8 The code for ‘space requires matter’ is ‘813’.
