A cricketer scored 142 runs which included 12 boundaries and 2 sixes. What percent of his total score did he make by running between the wickets.
[ "70%", "None of these", "57.75%", "54.54 %" ]
C
Explanation : Number of runs made by running = 142 - (12 x 4 + 2 x 6) = 142 - (60) = 82 Now, we need to calculate 82 is what percent of 142. => 82/142 * 100 = 57.75 % Answer : A

Do placental mammals give birth to relatively small or large fetuses?
[ "small", "neither", "large", "they don't give birth" ]
C
Placental mammals give birth to a relatively large and mature fetus. This is possible because they have a placenta to nourish the fetus and protect it from the mother’s immune system. This allows for a long period of growth and development before birth.

If x and y are two-digit integers such that x > 30 and y<70, which of the following is closest to the minimum value of xy?
[ "310", "4,000", "700", "28,000" ]
A
To get the minimum possible value of xy, we need minimize the value of both x and y min x can be = 31 (given x is a two-digit integer > 30) min y can be = 10 (given y is a two-digit integer < 70) xy = 31*10 = 310 Answer (D)

Like acetic acid, pentanoic acid is what kind of acid?
[ "carbonic", "hydroxyl", "amino", "carboxylic" ]
D
Like acetic acid, pentanoic acid is a carboxylic acid. Unlike acetic acid, however, the alkyl group is rather large, consisting of a 4-carbon chain as in butanol. As with butanol, the nonpolar character of the alkyl group is likely to be as important as the polar character of the carboxylic acid group, making it unlike...

Two trains, each 100 m long, moving in opposite directions, cross other in 12 sec. If one is moving twice as fast the other, then the speed of the faster train is?
[ "40 km/hr", "66 km/hr", "67 km/hr", "76 km/hr" ]
A
Let the speed of the slower train be x m/sec. Then, speed of the train = 2x m/sec. Relative speed = ( x + 2x) = 3x m/sec. (100 + 100)/12 = 3x => x = 50/9 So, speed of the faster train = 100/9 = 100/9 * 18/5 = 40 km/hr. Answer:C
