Forty per cent of all those who applied for the job had experience. If 80 people had experience, how many applied, in total?

total people = X = 200

Step-by-step explanation:

total people = X = 200

People having experience = 80

Percent haing experience = 40 % = 40 / 100

40/ 100  x X = 80

x= 80  x 100 / 40 = 200

I hope im right!!

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
