Sum of first n natural numbers is n (n+1) / 2
For n=10, sum = 10*11/2 = 55

In jar A there are 3 white balls and 2 green ones, in jar B there is one white ball and three green ones. A jar is randomly picked, what is the probability of picking up a white ball out of jar A?
The probability of picking the jar A is ½. T
he probability of picking up a white ball out of jar A Is 3/(3+2) = 3/5.
The probability of both events is 1/2 * 3/5 = 3/10.

If x and y are positive numbers and a 50 percent increase in x and 20 percent decrease in y would result in how much percentage changes in z , where Z = xy?
Given Z = XY
When X becomes 1.5 X and Y becomes 0.8 Y
We get Z = 1.5X * 0.8Y = 1.2 XY
Hence, Z will increase by 20%.

If the sum of 5, 8, 12, and 15 is equal to the sum of 3, 4, x, and x + 3, what is the value of x?
: Forming the equation:
5 + 8 + 12 + 15 = 3 + 4 + x + x + 3

Aaron will jog from home at x miles per hour and then walk back home by the same route at y miles per hour. How many miles from home can Aaron jog so that he spends a total of t hours jogging and walking?
: We know, speed = distance/ time And distance travelled while jogging (D1) = distance travelled while walking (D2)
While jogging, Â Â X= D1 / t1 While walking, Â Â Y = D2 /t2
Also, t = t1 + t2
Since, D1=D2, we get Xt1 = Yt2
t1 + t2 = t (given) =>;   t1 + X/Y*t1 =t   =>; t1 = Y*t /(X+Y)
Total distance travelled, D = D1 + D2 = X*t1 + Y*t2 Â Â = 2 *X*t1 (since Xt1=Yt2
=>; D = 2 *X*Y.t(X+Y) Â Â =>; D = 2XYt /(X+Y)
Hence, distance aron jogs= D1 = D/2 = XYt /(X+Y)

If Juan takes 11 seconds to run y yards, how many seconds will it take him to run x yards at the same rate?
: Speed = Distance / Time
To run X yards, time required = X/speed = X/ (y/11) = 11X/y

The probability of pulling a black ball out of a glass jar is 1/X. The probability of pulling a black ball out of a glass jar and breaking the jar is 1/Y. What is the probability of breaking the jar?
Let Z be the probability of breaking the jar, therefore the probability of both events happening is Z * (1/X) = (1/Y) (given in second probability)

A certain road trip was completed in two parts interrupted by an hour-long lunch break. During the first portion of the trip the average speed was 55 miles per hour and the average speed during the second part of the trip was 63 miles per hour. If the trip was 480 miles long and took a total of 9 hours then which of the following is the amount of time spent driving before the lunch break?
Speed = Distance / Time
Since the lunch time was one hour, deducting it from the total trip time, we get travel time:
9 – 1 = 8 hrs
Using the equation above, Time * Speed = Distance
Let the time taken to complete the first part = x hrs
Time taken to complete second part = 8 – x hrs
For first half:
Distance = Time * Speed = x * 55

How many 3-digit numbers satisfy the following conditions:
For the first digit you have 9 options (from 1 to 9 with out 0), for the second number you have 9 options as well (0 to 9 minus the first digit that was already used) and for the third digit you have 8 options left. So the number of possibilities is 9 x 9 x 8 = 648.

Left in the park to fend for itself, the dog’s hunger drove the normally friendly animal to growl at each person that walked by.
23 / 24
If 4 is one solution of the equation x2 + 3x + k = 10, where k is a constant, what is the other solution?
Since 4 is one of the roots, substituting 4 in x2 + 3x + k = 10 gives
16+12 +k = 10 =>; K=-18
So equation is, x2 + 3x -18 =10 =>; x2 + 3x -28 = 0=>; x2  +7x -4x  - 28 = 0=>; X = -7 and 4
