The population of a town is 45000; 5/9th of them are males and the rest females 40% of the males are married. What is the percentage of married females?

A. 60%
B. 50%
C. 45%
D. 40%
Explanation:
Male = 45,000* 5/9 = 25,000
Female = 45,000* 4/9 = 20,000
Married Male = 25,000* 40/100 = 10,000
Married Female = 10,000
20,000 ———— 10,000
100 ————- ? => 50%

The ratio of numbers is 3:4 and their H.C.F is 4. Their L.C.M is__________?

A. 12
B. 16
C. 24
D. 48

Two balls can be picked from nine balls in ⁹C₂ ways.
We select one white ball and one red ball from five white balls and four red balls. This can be done ⁵C₁ . ⁴C₁ ways.
The required probability = (5 * 4)/⁹C₂ = 20/36 = 5/9
