A completes 2/5 part of a work in x days. After then he calls B and they together finish the remaining work in 6 days. If B alone takes 100/6 days. Then find the value of x.

(a) 10 days

(b) 50/3 days

(c) 20 days

(d) 40 days

Let's break this problem down step by step:

### Step 1: Work Done by A in \( x \) Days

- A completes \( \frac{2}{5} \) of the work in \( x \) days

A completes 2/5 part of a work in x days. After then he calls B and they together finish the remaining work in 6 days. If B alone takes 100/6 days. Then find the value of x.
(a) 10 days
(b) 50/3 days
(c) 20 days
(d) 40 days

Solve a work and time problem where A completes 2/5 of a work in x days, and together with B, they finish the rest in 6 days. B alone takes 100/6 days. Learn how to calculate the value of x using the rate of work formulas. Suitable for Grades 8-10.
