[amp_mcq option1=”45 years” option2=”40 years” option3=”35 years” option4=”30 years” correct=”option1″]<\/p>\n
The correct answer is (a).<\/p>\n
Let $x$ be the age of the man and $y$ be the age of his son. We are given that the ratio of their ages is 3:1, so $x = 3y$. We are also given that after 15 years, the age ratio will be 2:1, so $(x + 15) = 2(y + 15)$. Substituting $x = 3y$ into this equation, we get $3y + 15 = 2(y + 15)$. Simplifying, we get $y = 15$. Substituting $y = 15$ into $x = 3y$, we get $x = 45$.<\/p>\n
Option (b) is incorrect because $40$ is not a multiple of $15$. Option (c) is incorrect because $35$ is not a multiple of $15$. Option (d) is incorrect because $30$ is not a multiple of $15$.<\/p>\n","protected":false},"excerpt":{"rendered":"
