Two pipes A and B can fill a tank in 4 and 5 hours respectively. If they are turned up alternately for one hour each, the time taken to fill the tank is?

Two pipes A and B can fill a tank in 4 and 5 hours respectively. If they are turned up alternately for one hour each, the time taken to fill the tank is?

A. 2 hrs 15 min
B. 4 hrs 24 min
C. 5 hrs
D. 3 hrs
Explanation:
1/4 + 1/5 = 9/20
20/9 = 2 2/9
9/20 * 2 = 9/10 —- 4 hours
WR = 1 – 9/10 = 1/10
1 h —- 1/4
? —– 1/10
2/5 * 60 = 24 = 4 hrs 24 min

A cuboidal, block of 6 cm X 9 cm X 12 cm is cut up into an exact number of equal cubes. The least possible number of cubes will be_________?

A cuboidal, block of 6 cm X 9 cm X 12 cm is cut up into an exact number of equal cubes. The least possible number of cubes will be_________?

A. 6
B. 9
C. 24
D. 30
Volume of block = (6 X 9 X 12) cm3 = 648 cm3.
Side of largest cube = H.C.F. of 6 cm, 9 cm, 12 cm = 3 cm.
Volume of this cube = (3 X 3 X 3) = 27 cm3.
Number of cubes = 648/27 = 24.

A rectangular field has dimensions 25m by 15m. Two mutually perpendicular passage of 2m width have been left in it’s central part and grass has been grown in rest of the field. The area under the grass is____________?

A rectangular field has dimensions 25m by 15m. Two mutually perpendicular passage of 2m width have been left in it’s central part and grass has been grown in rest of the field. The area under the grass is____________?

A. 295m2
B. 299m2
C. 300m2
D. 375m2
Explanation:
Area under the grass = [(25 x 15) – {(25 x 2)+ (15 x 2) – (2 x 2)}] Sq.m
= [375 –(50 +30 -4)]Sq.m =(375 – 76)Sq.m = 299 Sq.m
