Ganesh to complete the work, if he works alone.​

Answer 1

Answer:

work done by ganesh=10days

Step-by-step explanation:

let the work did by gajanan be X

work did by ganesh=y

work did by ganesh=10y

x+y=12......1

x-10y=0

x-y=10.......2

add eq 1 and 2

x+y=12

(+) x-y=10

-----------

2x=22

-----------

2x=22

x=22/2

x=11

work did by gajanan=11days

sub x=11 in eq1

11+y=12

y=12-11

y=1

work did by ganesh=10×1

=10days
