Answer to Problem 18WE
Explanation of Solution
Given:
Jim weighs more than Joe but less than Jack. Their weights in kilograms are consecutive multiples of 7.
If each weighed 5 kg less, the sum of the weight is 195 Kg.
Calculation / Explanation:
Given that the weight of Jim, Joe and Jack are consecutive multiples of 7.
Therefore, the weights are
Given that Jim weighs more then Joe but less than Jack.
Joe>Jim>Jack
Therefore, the weight of Jim is
Given that if each weigh 5 Kg less, the sum of their weights is 195 Kg.
Hence,
The weight of Jim is
The weight of Jack is
The weight of Joe is
The sum of their weight is 195.
Conclusion:
Therefore, the relationship is
