Q10 If a man’s rate with the current is 12 km/hr and the rate of current is 1.5 km/hr, then the man’s rate against the current is
a) 9 km/hr b) 6.75 km/hr c) 5.25 km/hr d) 7.5 km/hr e) None of theseAnswer & Explanation
- (c); Man’s rate upstream=16/5 km/hr
Man’s rate downstream=27/5 km/hr
Velocity of the current=1/2 (27/5-16/5) km/hr=1.1 km/hr
(d); Rate downstream=(2/15 *60) km/hr=8 km/hr
Rate upstream=5 km/hr
Velocity of the current=1/2 (8-5) km/hr=1.5 km/hr
(b); Rate downstream=1/10 *60=6 km/hr
Rate upstream=1/30 *60=2 km/hr
Velocity of the stream=1/2 (6-2)=2 km/hr
(b); Rate upstream=3/4 * 4/45 * 60=4 km/hr
Rate downstream=3/4 * 2/15 * 60=6 km/hr
Speed of the man in still water (6+4)1/2=5 km/hr
Speed of the stream=(6-4) ½=1 km/hr
(a); Rate downstream=48/8 =6 km/hr
Rate upstream= 48/12 = 4 km/hr
- (c); 1/2 (11-7)=2 km/hr
- (c); U=11/5, D=26/5
Y=1/2 (26/5 – 11/50) =1.5 km/hr
(a); D=60/6 =10 km/hr
Y= 1/2 (10-6)=2 km/hr
- (c); D=15 km/hr
(a); D=12 km/hr
