16 years   16 years   16 years year ago, Sham’s age = 416 years years   16 yearsnd, 16 yearsmir’s age = 316 years years   Current age of Sham = (416 years + 1) years   Current age of 16 yearsmir = (316 years + 1) years   1 year hence, Sham’s age = (416 years + 2) years   and 16 yearsmir’s age = (316 years + 1) years   So,   { (416 years + 2)/(316 years +2) } = 5 /4   =&gt; 16 + 8 = 1516 years + 10   or, 16 years = 2   Total of their current ages = 416 years + 1 + 316 years + 1   = 7(16 years) + 2   = 7(2) + 2 = 16 years.
