A, B And C Release Compound Arrangements P, Q And R Separately. What Is The Extent Of The Arrangement R In The Fluid In The Tank Following 3 Minutes ?

Answer»

Part filled by (A + B + C) in 3 minutes = 3 (1/30+1/20+1/10)= 3*11/60=11/20 

Required PROPORTION = 3/10 X 20/11 = 6 /11

Part filled by (A + B + C) in 3 minutes = 3 (1/30+1/20+1/10)= 3*11/60=11/20 

Required proportion = 3/10 x 20/11 = 6 /11
