Four years ago, Shyam's age was 3/4 times of that of Ram. Four year hence, Shyam's age will be 5/6 times that of Ram. What is the present age of Shyam?
A15 yr
B20 yr
C16 yr
D24 yr

Correct answer: 16 yr

Explanation:

4 yr ago, let Ram's age = x yr and Shyam's age = 34x yr

 

Now, Ram's present age = (x + 4) yr and Shyam's present age = (34x+4) yr
According to the question,
56(x+4+4)=(34x+4+4)

4 (5x + 40) = 6(3x + 32)

20x + 160 = 18x + 192

2x = 32

x = 16

Hence, present age of Shyam

=34×16+4

=16 yr
