The sum of three consecutive even numbers is 42. Find the middle number of the three? | [
"25",
"32",
"14",
"15"
] | C | Answer: Option A
Three consecutive even numbers (2P - 2), 2P, (2P + 2).
(2P - 2) + 2P + (2P + 2) = 42
6P = 42 => P = 7.
The middle number is: 2P = 14. | AquaRat_train |

The average of runs of a cricket player of 20 innings was 32. How many runs must he make in his next innings so as to increase his average of runs by 8 ? | [
"200",
"96",
"122",
"128"
] | A | Average = total runs / no.of innings = 32
So, total = Average x no.of innings = 32 * 20 = 640
Now increase in avg = 4 runs. So, new avg = 32+8 = 40 runs
Total runs = new avg x new no. of innings = 40 * 21 = 840
Runs made in the 11th inning = 840-640 = 200

Suppose that the angle between the minute hand and hour hand of a
clock is 60o. If the minute hand is 16 inches long and the hour hand is
10 inches long, then what is the distance between the tip ends of the
hands in inches? | [
"10",
"12",
"14",
"13"
] | C | This is a direct application of the Law of Cosines with two sides of a triangle
having lengths 10 inches and 16 inches and the angle between them being 60. If x denotes
the distance between the tips of the hands in inches, then
x2<-(square) = 102 +16-2<-(square)-2*10*16cos(60o)= 100 + 256-160 = 196
Hence, x = 14.

For a finite sequence of non zero numbers, the number of variations in the sign is defined as the number of pairs of consecutive terms of the sequence for which the product of the two consecutive terms is negative. What is the number of variations in sign for the sequence 10, -3, 20, 5, -4, 6, -7 , 12? | [
"4",
"1",
"2",
"5"
] | D | The questions basically asks: how many pairs of consecutive terms are there in the sequence such that the product of these consecutive terms is negative.
10*(-3)=-30=negative;
-3*20=-60=negative;
5*(-4)=-20=negative.
6 * (-7) = -42 > negative
-7 * 12 = -84 >>negative
So there are 5 pairs of consecutive terms.

a^3 = 21 × 25 × 45 × d
=> a^3 = (7*3) x (5*5) x ( 3^2 * 5) x d

The length of a rectangular floor is more than its breadth by 200%. If Rs. 324 is required to paint the floor at the rate of Rs. 3 per sq m, then what would be the length of the floor? | [
"10",
"19",
"12",
"18"

l = b + 200% of b = l + 2b = 3b
Area of the floor = 324/3 = 108 sq m
l b = 108 i.e., l * l/3 = 108
l2 = 324 => l = 18.
