There is some profit when an article is sold for rupees 860. However when the same article is sold for rupees 560 there is some loss. If the quantum of profit is 2 times the quantum of loss find the cost price of an article?

if x = 1, then the answer is 3.5

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
