SDeep Bhattacharya   11 years AGO

{64*(.04)-.12*(140)}/96= -(x/100)
solving this we get
x=89/6.
so option 6) 89/6

somya kulshrestha   11 years AGO

ans. is 89/6
(4/100)*64 + (x/100)*96 = (12/100)*140
thus
(x/100)*96 = (12/100)*140 - (4/100)*64
solving we get
x= 89/6

4%of64 + x%of96 = 12%of140
=>(4/100)*64 + (x/100)*96 = (12/100)*140
=>64/25 + 24x/25 = 84/5
=>24x/25 = 84/5 - 64/25
=>x=89/6
