Question

saleem solves 2/3rd of his work in 2 1/3 hours how log will it take to complete his entire work?

Answer 1

Answer:

Saleem will take 3 1 / 2 hours to complete his entire work.

Step-by-step explanation:

Given, Saleem solves 2 / 3 rd of his work in 2 1 / 3 hours.

It means :

= > Time taken be Saleem to solve 2 / 3 rd of his work = 2 ( 1 / 3 ) hours

= > Time taken by Saleem to solve 2 / 3 rd of his work = ( 6 + 1 ) / 3 hours

= > Time taken by Saleem to solve 2 / 3 rd of his work = 7 / 3 hours

= > 2 / 3 x time taken by Saleem to solve his total work = 7 / 3 hours

= > Time taken by Saleem to solve his work = 7 / 3 hours x 3 / 2 = 7 / 2 hours

= > Time taken by Saleem to solve his work = 7 / 2 hours or 3 1 / 2 hours or 3.5 hours or 3 hours 30 minutes.

Hence,

Saleem will take 3 1 / 2 hours to complete his entire work.

Answer 2

Solution:

=> Saleem solves $\dfrac{2}{3}$rd of his work in 2 × $\dfrac{1}{3}$ hours.

=> $\dfrac{3\:\times\:2\:+\:1}{3}$

=> $\dfrac{6\:+\:1}{3}$

=> $\dfrac{7}{3}$

Saleem takes $\dfrac{7}{3}$ hours to complete his $\dfrac{2}{3}$rd of the work.

• Time taken by him (Saleem) to complete his entire work = $\dfrac{7}{3}$ × $\dfrac{3}{2}$

=> $\dfrac{7}{2}$ hours.

Saleem takes $\dfrac{7}{2}$ or 3 $\dfrac{1}{2}$ hours to complete his entire work.
