Answer 1

Answer:

General Rules for this type of sums:

(i) Suppose if a person A can finish a work in n days.

Then, work done by A in 1 day = 1/nᵗʰ part of the work.

(ii) Suppose that the work done by A in 1 day is 1n

Then, time taken by A to finish the whole work = n days.

Step-by-step explanation:

Let A be billy and B be Jodah.

Time taken by (A + B) to finish the work = 15 days.

Time taken by B alone to finish the work 20 days.

(A + B)’s 1 day’s work = ¹/₁₅

and B’s 1 day’s work = ¹/₂₀

A’s 1 day’s work = {(A + B)’s 1 day’s work} - {B’s 1 day’s work}

= (¹/₁₅ - ¹/₂₀) = (4 - 3)/60 = ¹/₆₀

Therefore, A alone can finish the work in 60 days.
