Bart has $150,512 dollars in his bank account. He wants to split this money evenly among his nine daughters. What is the least amount of money (in whole number of dollars) that he must remove from his account? | [
"6",
"2",
"5",
"4"

In a 500 m race Dishu beats Abhishek by 100 m or 5 seconds. In another race on the same track at the same speeds. Abhishek and Prashant start at one end while Dishu starts at the opposite end.

"240 m",
"250 m",
"100 m",
"560 m"
] | B | Explanation :
Abhishek's speed = 100/5=20 m/s.
Time taken by Abhishek to cover 500 m =500/20=25 seconds.
Dishu's speed = 500/20 or 25 m/s
Prashant's speed = 15 m/s
Time taken by Dishu to meet Prashant in 500m race in opposite direction:
Distance covered by Abhishek:
=>500/(15+25).
=>12.5 sec.
=>12.5(20)= 250 m.

The captain of a cricket team of 11 members is 26 years old and the wicket keeper is 3 years older. If the ages of these two are excluded, the average age of the remaining players is one year less than the average age of the whole team. What is the average age of the team? | [
"23 years",
"20 years",
"24 years",
"21 years"
] | A | Explanation:
Let the average age of the whole team by x years.
11x – (26 + 29) = 9(x -1)
11x – 9x = 46
2x = 46
x = 23.
So, average age of the team is 23 years.

At 1:00 pm, there were 10.0 grams of bacteria. The bacteria increased to x grams at 4:00 pm, and 22.5 grams at 7:00 pm. If the amount of bacteria present increased by the same fraction during each of the 3-hour periods, how many grams of bacteria were present at 4:00 pm? | [
"15.3",
"15.6",
"15.0",

At 4:00 pm, the amount of bacteria was 10x and at 7:00 pm it was 10x^2.
10x^2 = 22.5
x^2=2.25
x=1.5
At 4:00 pm, the amount of bacteria was 10(1.5)=15 grams.
