The marked price of the watch is Rs 4875 and the cost price is Rs 3750

Explanation:

Let the cost price of the watch be Rs. y and the marked price of the watch be Rs. x.

The marked price of a watch is 30% above the cost price, therefore the marked price of the watch (x) = y + 30% × y = y + 0.3y = 1.3y.  

The watch is sold at 20% discount, this means it is sold at x - 20% × x = x - 0.2x = 0.8x.

When sold at 20% discount, there is a gain of Rs 150. Therefore:

0.8x = 150 + cost price

0.8x = 150 + y

but x = 1.3y

0.8(1.3y) = 150 + y

1.04y = 150 + y

1.04y - y = 150

0.04y = 150

y = 3750

Since x = 1.3y = 1.3(3750) = 4875

Therefore the marked price of the watch is Rs 4875 and the cost price is Rs 3750

normally working animals are domesticated and ruled by a master, a domesticator (tamer), to perform basic and important functions on a farm, for example. the value used in this context is animal labor in exchange for food. it is not so much a contrast to the story told by napoleon and the pigs, since the animals of that particular farm also performed functions on the farm through domestication. the only thing is that in this case, who rules them is a pig, also an animal, but very respected, to whom the other animals lent him submission. that's about a strong relationship of dependency between animal and owner.
