By selling a watch on 400 and 460’. Loss and profit happened respectively.if the loss and profit are equal, find cp.

Maslowich

Answer:

430

Step-by-step explanation:

Given :-

By selling a watch on 400 and 460’. Loss and profit happened respectively.
The loss and profit are equal.

And we need to find out the CP .So ,

Let :-

CP be x
Profit and Lost be y .

According to the Question :-

$:\implies$ 460 = x + y ( Profit)

$:\implies$ 400 = x - y ( Loss)

Adding both :-

$:\implies$ 460 + 400 = x + y + x - y

$:\implies$ 860 = 2x

$:\implies$ x = 860/2

$:\implies$ x = 430

Hence the Cost price of the watch is 430 .

Hund’s rule of maximum multiplicity specifies that _____. A. electrons will fill orbitals of lower energy first, pairing up only

djverab [1.8K]

Answer:

A. electrons will fill orbitals of lower energy first, paring up only after each orbital of the same energy already has one electron

Step-by-step explanation:

The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.
