Ten years ago A was half of B in age. If the ratio of their present ages is 3 : 4, what will be the total of their present ages
Choose the correct answer
A) 65 years B) 35 years C) 55 years D) 44 years E) 11 years
Let A's age 10 years ago = x years.   Then, B's age 10 years ago = 2x years.   (x + 10) / (2x+ lO) = 3/4   =&gt; x = 5.   So, the total of their present ages =(x + 10 + 2x + 10)   = (3x + 20) = 35 years.   Answer: 35 years
