Question

A can finsh the work in 18 days ang B can do the work in half the time takes A what part of same work they can finish in a day​

Answer 1

Answer:

A can do the work = 18 days

B can do the work = 18/2=9days

(A+B)'s 1 day work =1/18 + 1/9 = 1/6

=>in 3 days = 3×1/6 = 1/2 work is completed

Half work is the answer

Answer 2

$\boxed {\underline {\mathbb {COMPLETE\:QUESTION:-}}}$

A can finish a work in 18 days and B can do the same work in half the time taken by A. Then working together what part of the same work can they finish in a day?

$\boxed {\underline {\mathbb {FINAL\:ANSWER:-}}}$

$\boxed {work\:compleated\:in\:a\:day=\frac{1}{6}}$

$\boxed {\underline {\mathbb {GIVEN:-}}}$

• A can finish the work in 18 days

• B can do the work in half the time takes A

$\boxed {\underline {\mathbb {TO\:FIND:-}}}$

what part of the same work can they finish in a day

$\boxed {\underline {\mathbb {SOLUTION:-}}}$

A can finish a work in 18 days.

B can finish a work in 9 days.

So In one day  A can finish $\frac{1}{18}$  work.  

and In one day  B can finish $\frac{1}{9}$ work  

So, working together the work can they finish in a day.

W=A+B

$work=\frac{1}{18}+\frac{1}{9}\\\boxed {work=\frac{1}{6}}$
