The farmer skillfully divides the cattle

If the farmer leaves x head of oxen, then his wife will have (x 2+1 2) head of oxen; The eldest son received [x-(x 2+1 2)] 2+1 2 oxen, which were reduced to (x 4+1 4) heads; In the same way, the second son gets (x 8 + 1 8) head of ox; The eldest daughter's share of cattle was (x 16 + 1 16). The total number of cattle divided should be equal to the total number of cattle left by the farmer, so the following equation can be established: (x 2+1 2)+(x 4+1 4)+(x 8+1 8)+(x 16+1 16)=x

x = 15, i.e. the farmer left a total of 15 cows.

The eldest son actually got half of the last remaining ox and added half, but not a single head was killed, and there was no left, and the eldest daughter received: 1 head.

The second son gets: (1+ heads, the eldest son gets: (2 丨 heads, the wife gets: (4 2 1 丨 2 4 8 heads.)

Total: 1 2 4 8 15 heads.

Answer: When the farmer died, he left behind 15 cows, one for the eldest daughter, two for the second son, four for the eldest son, and eight for the wife.

There was a farmer who kept a very docile and obedient old ox. He loves this cow very much, because no matter he comes home from **, he can lie on the car and sleep, and the old ox can naturally send him home safely, so he never beats and scolds the old cow, and rarely restrains it with reins.

Unfortunately, ten years later, the old ox died of old illness, and the farmer cried very sadly and vowed never to raise cattle again. However, once he saw an old ox that was exactly the same as his dead in the market, and he was so surprised that he thought to himself, "Isn't my old ox resurrected again?" , so he thought about buying it back.

The cow seemed to be docile and obedient, which made him even more happy. Imagine that it was really his old scalper who was resurrected.

It is said that on this day, he returned from the bazaar again and habitually fell asleep. The newly-bought old ox still walked forward, but the more he walked, the more uncomfortable he became, for he was accustomed to hearing the farmer's shouting, and suddenly there was no sound, and his heart was at a loss.

Suddenly, a mad dog came at it on the side of the road, and the scalper was frightened and ran in a hurry. The farmer was awakened by the barking and jolting of the dogs, and saw that the old ox had run to the bridge, and at this moment a car happened to be driving on the opposite side, and the farmer hurriedly shouted, but the old ox seemed to be deaf and could not hear at all.

The old ox was still running forward frantically, and it was too late for the farmer to dodge. I saw that the cow instinctively turned sideways when he saw the car, and he dodged it.

However, the wheel was scraped on the railing of the bridge because of this evasion, and one railing was hung up, and the other railing jammed the wheel, and the old ox was taken by the stuck wheel to the side, just over the railing and into the surging river.

The car dodged the oxen and the ox cart, but because it couldn't dodge, it crushed the mad dog in hot pursuit. The driver stopped the car and glanced at the mad dog, then hurried to the farmer's side, and he was relieved to see that the farmer was not injured.

Although the farmer did not suffer any external injuries, he did suffer serious internal injuries in his heart. In a fit of rage, he pushed the ox cart off the bridge. After the push, the farmer burst into tears like a child and vowed never to raise cattle again.
