10/6¹/4 = 8/5
8/5 a+b +c ka efficiency he
a+b = 1 he , a+c+c = 8/5 he efficiency ,to c ka nikal jayega 3/5
question me diya he c or a ka efficiency same he to a ka bhi efficiency 3/5
ok
a+b =1 he , a ka 3/5 to fir b ka efficiency hoga 2/5
thanks
c = total work/ efficiency of c = 12/5/2
= 60/2 = 30 will be the answer
thanks
