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
