Puzzle on Barter System


Three countrymen met at a cattle market. ‘Look here,’ said Hari to Jaggu, ‘I’ll give you six of my pigs for one of your horses, and then you’ll have twice as many animals here as I’ve got.’

‘If that’s your way of doing business,’ said Dinanath to Hari, ‘I’ll give you fourteen of my sheep for a horse, and then you’ll have three times as many animals as I.’

‘Well, I’ll go better than that,’ said Jaggu to Dinanath; ‘I’ll give you four cows for a horse, and then you’ll have six times as many animals as I’ve got here.’

No doubt this was a very primitive way of bartering animals, but  it is an interesting little puzzle to discover just how many animals Jaggu, Hari and Dinanath must have taken to the cattle market.

Mr. Moody grumbles about bad time-keeping of trains from morning till night!

On one particular morning he was quite justified.

His train left on time for the one hour journey, to Clarksville, and it arrived 5 minutes late.
However, Mr. Moody ‘s watch showed it to be 3 minutes early, so he adjusted his watch by putting it forward 3 minutes.

His watch kept time during the day, and on the return journey in the evening the train started on time, according to his watch, and arrived on time, according to the station clock.
If the train travelled 25 percent faster on the return journey than it did on the morning journey, was the station clock fast or slow, and by how much?
