Question

119. In an office, 40% of the staff is female, 70% of the female
staff and 50% of the male staff are married. The percentage of
the unmarried staff in the office is?​

Answer 1

Answer:

42% is the answer friend

Step-by-step explanation:

let the total staff be 100

40% of 100 = 40

100 - 40 = 60

70% female staff are married

70% of 40 =

40 x 70/100 = 28

50% male staff are married

50% of 60 =

60 x 50/100 =30

so now,

28+30 = 58

so 58% staff are married  (because 58% of 100 = 58)

so now =

unmaaried staff =

100-58= 42

so your answer is 42% friend
