A mixed doubles tennis game is to be played two teams(each consists of one male and one female) There are four married couples. No team is to consist a husband and his wife. What is the maximum number of games that can be played?A. 12
B. 48
C. 36
D. 42
Explanation:
Married couples = MF MF MF MF
AB CD EF GH
Possible teams = AD CB EB GB
AF CF ED GD
AH CH EH GF S
Since one male can be paired with 3 other female, Total teams = 4×3 = 12.
Team AD can play only with CB,CF,CH,EB,EH,GB,GF(7 teams )
Team AD cannot play with AF, AH, ED and GD
The same will apply with all teams, So number of total matches = 12×7 = 84.
But every match includes 2 teams, so the actual number of matches = 84/2 = 42.The word Geometry has been derived from two Greek words:_____________?
The word Geometry has been derived from two Greek words:_____________?A. Geo means Earth
B. Metron means Measurement.
C. Hence Geomatery means
D. Earth measurementWalking 6/7th of his usual speed, a man is 12 minutes too late. What is the usual time taken by him to cover that distance?
Walking 6/7th of his usual speed, a man is 12 minutes too late. What is the usual time taken by him to cover that distance?A. 1 hr 42 min
B. 1 hr
C. 2 hr
D. 1 hr 12 min
New speed = 6/7 of usual speed
Speed and time are inversely proportional.
Hence new time = 7/6 of usual time
Hence, 7/6 of usual time – usual time = 12 minutes
=> 1/6 of usual time = 12 minutes
=> usual time = 12 x 6 = 72 minutes
= 1 hour 12 minutesIf the length, breadth and the height of a cuboid are in the ratio 6: 5: 4 and if the total surface area is 33300 cm2, then length breadth and height in cms, are respectively?
If the length, breadth and the height of a cuboid are in the ratio 6: 5: 4 and if the total surface area is 33300 cm2, then length breadth and height in cms, are respectively?A. 90, 85, 60
B. 85, 75, 60
C. 90, 75, 70
D. 90, 75,60
Explanation:
Length = 6x
Breadth = 5x
Height = 4x in cm
Therefore, 2(6x × 5x + 5x × 4x + 6x × 4x) = 33300
148×2 = 33300
=> x2 = 33300/148 = 225
=> x = 15.
Therefore, Length = 90cm,
Breadth = 75cm,
Height = 60cm
