If (2x + 1) times (x + 4) is an odd integer, then x must be: | [
"a composite number",
"a negative integer",
"an odd integer",
"a prime number"
] | C | Solution:
(2x + 1) times (x + 4) means (2x + 1)(x + 4)
(2x + 1)(x + 4) = 2x^2+9x+4
For 2x^2+9x+4 to be odd, 9x+4 must be odd since 2x^2 is always even.
So 9x must be odd, hence x must be odd.
Therefore x is an odd integer.

At the opening of a trading day at a certain stock exchange, the price per share of stock K was $15. If the price per share of stock K was $16 at the closing of the day, what was the percent increase in the price per share of stock K for that day? | [
"23.6%",
"5.9%",

A train 140 m long is running with a speed of 50 km/hr. In what time will it pass a man who is running at 4 km/hr in the direction opposite to that in which the train is going? | [
"8",
"7.0",
"9.33",
"9"
] | C | Speed of train relative to man = 50 +4 = 54 km/hr.

"7",
"12",
"6",
"-1"

When x < 3, x - 3 is negative, thus |x - 3| = -(x - 3). In this case we'll have (x - 3)^2 - (x - 3) = 20 --> x = -1 or x = 8. Discard x = 8 because it's not in the range we consider (< 3).
When x >= 3, x - 3 is non-negative, thus |x - 3| = x - 3.... | AquaRat_train |

A truck covers a distance of 376 km at a certain speed in 8 hours. How much time would a car take at an average speed which is 18 kmph more than that of the speed of the truck to cover a distance which is 14 km more than that travelled by the truck ? | [
"5 hours",
"6 hours",
"8 hours",
"7 hours"

Speed of the truck = Distance/time = 376/8 = 47 kmph
Now, speed of car = (speed of truck + 18) kmph = (47 + 18) = 65 kmph
Distance travelled by car = 376 + 14 = 390 km
Time taken by car = Distance/Speed = 390/65 = 6 hours.
