Question

a and b can do a piece of work in 30 days both work together for 10 day and with help of C they finished the work in next 10 days if 3 days work of B equal to 2 days work of C then in how many days A will finish a work​

Answer 1

Step-by-step explanation:

(A+B)'s one day work = 130130

(B+C)'s one day work = 124124

(C+A)'s one day work = 120120

Adding, we get

2(A+B+C)'s one day work

=130+124+120=4+5+6120=15120=18130+124+120=4+5+6120=15120=18

(A+B+C)'s one day work = 18×12=11618×12=116

(A+B+C)'s 10 days work = 10×116=1016=5810×116=1016=58

Remaining work = 1−58=381−58=38

A's one day work = (A+B+C)'s one day work - (B+C)'s one day work

= 116−124=3−248=148116−124=3−248=148

In one day A can do
