Question

Vivek, Rameshwar and Bhuvan divide a work
amongst themselves in the ratio of 2 : 3:5. Their
rates of work are in the ratio 1:2 : 3. It takes Vivek
12 days to complete his part. What is the amount of
work completed by them in 8 days from the start?​

Answer 1

Answer:

In 8 days they will complete 2/3 of there work.

Step-by-step explanation:

Given :

Three people with there divide work ratio

i.e.

Vivek = 2

Rameshwar = 3

Bhuvan = 5

so, total work is 2 + 3 + 5 = 10.

Rates of work are

Vivek = 1

Rameshwar = 2

Bhuvan = 3

vivek does 2/10 of work in 12 days.           ... Given

We will now calculate each of them per day work count.

formula : (Divine work done)/(total no of days to complete work)

For Vivek ,

≅ (1/10)/12 ∴ = 1/60

same for Rameshwar and Bhuvan respectively 1/30 and 1/20

Now , We will calculate their combined per day work.

i.e. (1/60) + (1/30) + (1/20) = (1+2+3) / 60

hence , In 8 day they will complete 8/12 = 2/3 of there work combine.
