Using the given information we can fill the following table Men Women Total Earn > 75000 75% of 40 = 30 (2/5) of 100 = 40 Earn ≤ 75000 Total 4 0 60 100 The table can be completed as below: Men Women Total Earn > 75000 30 10 40 Earn ≤ 75000 10 50 60 Total 4 0 60 100 From the table, 50 females out of 60 earn less or equal to$75000.
⇒ The required fraction = 5/6

I think, I deserve a kudus LOL

What fraction of the total females earn less than or equal to $75000? A) $$\frac{2}{3}$$ B) $$\frac{1}{6}$$ C) $$\frac{5}{6}$$ D) $$\frac{1}{2}$$ E) $$\frac{1}{5}$$ Men = 40% of total population Hence, Women = 60% of total population Now question says, 75% of the men earn greater than$75000 per annum

That means, 75% of 40% of men earn greater than $75000 per annum = 30% of all men ------ (1) Now question also says, $$\frac{2}{5}$$ of the people surveyed earned more than$75000 per annum.

Now $$\frac{2}{5}$$ of 100% = 40%

Out of the 40%, 30% are men --------- From (1)

That is remaining 10% are women. ----- (2)

Now we need to find,

fraction of the total females earn less than or equal to $75000. If 10% out of the 60% women earned more than$75000 per annum, then,

50% out of 60% women earned less than or equal to $75000 per annum. that makes it $$\frac{5}{6}$$ Hence C. _________________ Regards AD --------------------------------- A Kudos is one more question and its answer understood by somebody !!!

What fraction of the total females earn less than or equal to$75000?

A) $$\frac{2}{3}$$

B) $$\frac{1}{6}$$

C) $$\frac{5}{6}$$

D) $$\frac{1}{2}$$

E) $$\frac{1}{5}$$

Let the total Population be 100 , So Men = 40 & Women = 60

75% of the men ie 30 men earns > 75000

Further 2/5th (Or 40people ) earn > 75000 ; Or we have 10 women earns > 75000

Hence we have 50 women earning < 75000

Thus, the fraction of the total females earn less than or equal to \$75000 = 50/60 = 5/6, Answer must be (C)
