Question

Chiranji can do a work in 15 days, Natthi in 25 days and sumera in 30 days. How
long will they take to do the work if they work together?​

Answer 1

Answer:

11 days

Step-by-step explanation:

Lcm of 25 and 20 is 100. So total work = 100 units

Ranjith can do 4 units per day while anju can do 5 units per day

They together complete 5 days of work i.e 9 x 5 = 45 units

The remaining 55 units of work is done by anju in 55/5 days (or) 11 days

Answer 2

$\huge\mathtt{Answer}$

$Chiranji\:can\:do\:a\:work\:in\:=15Days$

$Natthi\:can\:do\:a\:work=25\:Days$

$Sumera\:can\:do\:a\:work\:in=30\:Days$

To find :-

Total time taken by them if they work together.

Total Time =$15+25+30$

Total time = $70\:Days$

•°• 70 Days will be taken by them if they work together
