Question
What was the age of Sonu 10 years ago? I. Ram
is seven years older than Sonu. II. The ratio of Ram’s present age to Sonu’s is 5:4. III. The difference between the age of Ram and that of Keshav is 12 years. The following questions are accompanied by three statements I, II and III.  You have to determine which statement(s) is/are sufficient/necessary to answer the questions.ÂSolution
Let Sonu’s present age be x years. ∴ Ram’s present age is (x + 7) years From II (x + 7)/x = 5/4 ∴ 4 x + 28 = 5 x x = 28 Hence, Sonu’s age 10 years ago = 28 – 10 = 18 years Thus, From I and From II, we can find the age of Sonu.Â
