A is twice as good at writing a novel as B. Together they can finish writing the novel in 24 days. In how many days can A alone write the novel? Correct Answer 36

Let the time taken by A to write a novel be x days

So, the time taken by B to write the novel is 2x days

According to question,

They together can finish the work in 24 days

⇒ 1/x + 1/2x = 1/24

⇒ 3/2x = 1/24

⇒ x = 36 days

∴ A can write the whole novel in 36 days
