The ratio of father`s age to his son`s age is 7:3 . The product of their age is 756. The ratio of their ages after 6 yr will be

a) 2:1
b) 5:2
c) 11:7
d) 13:9



Answer
Solution
Correct Answer Is : 2:1
Solution Is : Let the common ratio = x
Father`s age = 7x , son`s age = 3x
Now , from given condition
7x *3x = 756 ---> 21x2 = 756
x2 = 756/21 = 36 ---> x = √36 = 6
Father`s age = 7x6 = 42 yr
Son`s age = 3x6 = 18 yr
After 6 years
Father`s age = 42 + 6 = 48 yr
Son`s age = 18 + 6 = 24 yr
Required ratio = 48/24 = 2/1 = 2:1
The average age of 100 workers in a factory in 36.5 . The average age of the men is 45 and that of the women is 28. The number of women working in the factory is ,

a) 50
b) 45
c) 40
d) 60



Answer
Solution
Correct Answer Is : 50
Solution Is : Let the number of women = x
Number of men = 100 - x
Then , by given condition ,
28x + 45 ( 100 - x ) = 100 x 365
28 x + 4500 - 45x = 3650
17x = 850 = x = 850/17 = 50
Number of women = 50
