A batsman makes a score of 90 runs in the 17th inning and thus increases his averages by 3. What is his average after 17th inning? | [
"25",
"31",
"27",
"42"
] | D | Let the average after 17 innings = x
Total runs scored in 17 innings = 17x
Average after 16 innings = (x-3)
Total runs scored in 16 innings = 16(x-3)
Total runs scored in 16 innings + 90 = Total runs scored in 17 innings
=> 16(x-3) + 90 = 17x
=> 16x - 48 + 90 = 17x
=> x = 42

(B) We know that a # b = 100 and a # b = 4a² + 4b² + 8ab. So
4a² + 4b² + 8ab = 100
We can see that 4a² + 4b² + 8ab is a well-known formula for (2a + 2b)². Therefore
(2a + 2b)² = 100.
(2a + 2b) is non-negative number, since both a and b are non-negative numbers. So we can conclude that 2(a + b) = 10. ... | AquaRat_train |

"10",
"6",
"8",
"4"
] | D | We're told that N = 4P and that P is a prime number greater than 3. Let's TEST P = 4; so N = 16
The question now asks how many DIFFERENT positive EVEN divisors does 16 have, including 16?
16:
1,16
2,8
4,4
How many of these divisors are EVEN? 2,8,4,16…..4 even divisors.

If a certain sample of data has a mean of 31.0 and a standard deviation of 2.0, which of the following pairs contain two values that are each at least 2.5 standard deviations from the mean? | [
"(24.5; 38.0)",
"(27.0; 36.5)",
"(29.0; 32.5)",
"(26.5; 35.0)"

Sam’s car was fined when he gave Joe and Peter a ride, so they decided to help Sam pay the fine. Joe paid $7 more than 1/4 of the fine and Peter paid $7 less than 1/3 of the fine, leaving pay $12 less than 1/2 the fine to complete the payment. What fraction of the fine did Sam pay? | [
"$65",
"$45",
"$60",
"$50"
] | C | Call the fine F. Joe paid (1/4)F + 4 and Peter paid (1/3)F – 4, leaving (1/2)F – 5 left. If we add those three up, they should add up to F.
F = [(1/4)F + 7] + [(1/3)F – 7] + [(1/2)F – 12]
F = (1/4)F + (1/3)F + (1/2)F – 12
Multiply all terms by 12 to clear the fractions.
