Side Show is what it is trying to say. You can guess that because the word show is cornered to one side.
#1522 - Easy Number Grid Puzzle
Look at the attached picture and find out missing number on the grid.
The missing number is 60.
1 + 5 = 12
=> 1*2 + 5*2 = 12
2 + 10 = 24
=> 2*2 + 10*2 = 24
3 + 15 = 36
=> 3*2 + 15*2 = 36
Similarly,
5 + 25
=> 5*2 + 25*2 = 60
#1523 - Sports Logic Puzzle
A game is being played where eight players can last for seventy minutes. Six substitutes alternate with each player in this game. Thus, all players are on the pitch for the same amount of time including the substitutes.
For how long is each player on the pitch?
40 minutes
Total players = 8 + 6 = 14
Now, the question has told us that only eight players are present on the field at one time.
70 * 8 = 560 min in total.
Now dividing that with 14, we can conclude that each player was there on the pitch for 40 minutes (560/14)

#1525 - Coin Probability Problem
Three fair coins are tossed in the air and they land with heads up. Can you calculate the chances that when they are tossed again, two coins will again land with heads up?
50%
The vents in this case are independent. If you form the possible outcomes, they will be as follows
HHH
HTT
HHT
HTH
TTT
TTH
THT
THH
Now among these outcomes, four will give the required results. Thus the probability is 50%.
#1526 - Easy Number Sequence
Given that
(78)^9 = 6
And (69)^4 = 11
Can you find out (89)^2 = ?
7 + 8 = 15 and 15 - 9 = 6
6 + 9 = 15 and 15 - 4 = 11
Thus, (89)^2:
8 + 9 = 17 and 17 - 2 = 15
#1527 - Counting Triangles in a Figure

#1528 - Can You Solve This Math Problem
A rain drop fell from one leaf to another leaf and lost 1/4th of its volume. It then fell to another leaf and lost 1/5th of the volume. It again fell on another leaf and lost 1/5th of the volume.
This process kept repeating till it fell on the last leaf losing 1/75th of its volume.
Can you calculate the total percentage of loss from the initial volume when the drop has fallen to the last leaf accurate up to two decimal places?
4%
Let us assume that the initial volume of the water drop was k.
k - (1/4) k = (3/4) k
(3/4) k - (1/5) [(3/4) k] = (3/4) k * [1 - (1/5)] = (3/4) k * (4/5) = (3/5) k
(3/75) k = (1/25) k
1/25 = 4%
Thus, the answer is four percent.
#1530 - Interesting Math Question
Bobby and Wilbur decided to take their respective car out of the garage and race. None of them cheated and they both stood at the start time and decided to cover a distance in full throttle. The first to reach the mark was to be declared the winner.
Upon reaching the finishing mark, they found out that Bobby car is 1.2 times faster than Wilbur. Now, Wilbur had reached the mark about 1 minute and 30 seconds later than Bobby. Bobby car reached the mark at 60 MPH on average.
Can you calculate the distance between the starting mark and the final mark with the help of the given data?
7.5 Miles
(Speed of Bobby) = 60 MPH = 1.2 x (Speed of Wilbur) [MPH] = 1 M/ min
Thus (Speed of Wilbur) = 60/1.2 [MPH] = 50 [MPH] = 5/6 M/ min
(Time of Wilbur) = D [M] / (Speed of Wilbur) [M/min] = D/ (Speed of Wilbur) [min] = D/(5/6) min = 6D/5 min = 1.2 D min
(Time of Bobby) = D [M] / (Speed of Bobby) [M/min] = D/ (Speed of Bobby) [min] = D/(1) min = D min
Since (Time of Wilbur) - (Time of Bobby) = 1.5 min
Then (1.2 - 1) D min = 0.2D min = 1.5 min
Therefore D = 1.5/0.2 M = 1.5*5 = 7.5 Miles
