One year ago the ratio between Samir and Ashok’s age was 4:3. One year hence the ratio of their ages will be 5 :4. What is the sum of their present ages in years?
Choose the correct option
A) 12 years	B) 15 years	C) 16 years	D) Cannot be determined	E) none of these
Let their ages one year ago be 4x and 3x years.   (4x + 2)/(3x + 2) = 5/4   =&gt;4(4x + 2) = 5(3x + 2)   =&gt; x = 2   Sum of their present ages   = (4x + 1 + 3x + 1)   =(7x + 2) = 16 years   ANSWER:16 years
