Question

A does a work in 10 days and B does the same work in 15 days. In how many days they together will do

the same work?​

Answer 1

Step-by-step explanation:

A does in 10 days means A one day wOrk will be 1/10

similarly B one day work will be 1/15

now

A+B one day work = (1/10)+(1/15)

= 5/30

=1/6

now it's one day work, so to get the total number of days just write reciprocal of the work

that's reciprocal of 1/6 will b 6

so total number of days taken will be 6 days
