Question

( A-1 X )
( B-2 X )
here ( L C M ) is ( 2 X )
A's one day work is 2 unit
B's one day work is 1 unit
hence ( A+B ) one day work is 3 unit
( mathrm{A}+mathrm{B} ) can do a job in ( 2 mathrm{X} / 3 )
and we know, ( 2 mathrm{X} / 3=12 )
so ( 2 mathrm{X}=36 )
hence ( X=18 )
hence B complete the work in ( 2^{*} 18=36 ) days

# • If A complete some work in 6 days, B done the remaining work in 12 days. If ratio of time taken by A & B individually to complete a work is 2:3. The find the time taken by B alone to com READ ON APP
