Question 1122714
Vivek does {{{ 2/10 }}} of the work in {{{ 12 }}} days
His rate is {{{ (2/10)/12 = 1/60 }}}
Ramesh’s rate is:
{{{ 2*( 1/60 ) = 1/30 }}}
Bhuvan’s Rate is:
{{{ 3*( 1/60 ) = 1/20 }}}
————————————-
Let {{{ x }}} = the fraction of the work done in 8 days
{{{ (2/10)/(1/60) + (3/10)/(1/30) + (5/10)/(1/20) = 8/x }}}
{{{ 12 + 9 + 10 = 8/x }}}
{{{ 31 = 8/x }}}
{{{ x = 8/31 }}}
8/31 of the job gets done in 8 days

Definitely get a 2nd opinion on this ( if needed )
