Correct Answer - Option 4 : 30 years
Five years ago the ration of ages of Jam, Vihan and Mahesh = 3 : 4 : 5
Let;
Age of Jam five years ago = 3P
Present age of Jam = 3P + 5
Age of Vihan five years ago = 4P
Present age of Vihan = 4P + 5
Age of Mahesh five years ago = 5P
Present age of Mahesh = 5P + 5
According to question;
Total age of Jam, Vihan, and Mahesh at present = 75 years
Jam + Vihan + Mahesh = 75 years
(3P + 5) + (4P + 5) + (5P + 5) = 75
12P + 15 = 75
12P = 75 - 15 = 60
P = 5
So, the present age of Mahesh = 4P + 5
= 5 × 5 + 5
= 25 + 5
= 30 yaers
Hence, "30 years" is the correct answer.
