#384 - Simple Maths Problem
At a college election for president, exactly 963 votes were cast.
There are total of 4 candidates that participate in the election.
The winning candidate exceeds the opponents by 53, 79 and 105 votes.
How many votes do each candidate gets ?
Let us assume 'X' to be winner anN rest candidate are L, M & N
L = X - 53
M = X - 79
N = X - 105
X + X - 53 + X - 79 + X - 105 = 963
4X = 1,200
X = 300
L = 300 - 53
L = 247
M = 300 - 79
M = 221
N = 300 - 105
N = 195
Answer: X = 300, L = 247, M = 221, N = 195
Verify the ans
=> 300 + 247 + 221 + 195
=> 963

#387 - Easy Interview Age Puzzle
If we add four times the age of Dakota four years from now to five times her age five years from now we get ten times her current age.
How old will Dakota be three years from now?
If the current age of Dakota is x
4(x+4) + 4(x+5) = 10x
Thus x=41 years
After three years, Dakota will be 41+3 = 44 years
#388 - Distance Maths Puzzle
John was gifted a new Hayabusa. He drove x miles at 55mph. Then he drove x+20 miles at 40mps. He drove his bike for 100 minutes. How much distance did he travel?
t1 + t2 = 100 minutes = 100/60 hours
t1 = x/55
t2 = (x+20)/40
x/55 + (x+20)/40 = 100/60
x = 1540/57
Thus, Total distance = x + (x+20) = 4220/57 miles = 74 2/57 miles
