Ashok being the sleeping partner receives 1 10th of profit and the remaining is divided between pram...........

Explanation:

let total profit =x
ashok’s share in profit is (1/10)x
remaining profit = x= (1/10)x= (9/10)x
pramod’s share= 1/3 x (9/10)x = (3/10 )x
Prakash’s share= 2/3 x (9/10)x = (6/10)x
ashok – prakash= (6/10)x -(1/10)x = (5/10)x
5/10 x = 2,000 so, x= 4000
pramod’s share= (3/10) x 4000=1200
