Maths Brain Twister Puzzle

Maths Brain Twister Puzzle - 23 October

A research team went to a village somewhere between the jungles of Africa. Luckily for them, they reached on the day when quite an interesting custom was to be performed. The custom was performed once in a year as they confirmed and was performed in order to collect the taxes from every male of the region.

The taxes were to be paid in the form of grains. Everyone must pay pounds of grain equaling his respective age. Which means a 20 year old will have to pay 20 pounds of grains and a 30 years old will pay 30 pounds of grain and so on.

The chief who collects the tax have 7 weights and a large 2 pan scale to weigh. But there is another custom that the chief can weigh only with three of the seven weights.

Can you find out the weights of the seven weights? Also what is the maximum age of the man that can be weighed for the payment of taxes ?

    1. No. You can't make 14,16,20 (and others) with that sequence.

    2. 27-(9+3+1)=14
      (27+1)-(9+3)=16
      (27+3)-(9+1)=20
      hows that for an answer

    3. Dude, only 3 weights at a time are allowed.
      So, your answer is incorrect. If the question allowed 4 weights, then you are right.
