Solution:

ground + floor(Symbol)
= ground floor

Solution:

t1 + t2 = 100 minutes = 100/60 hours
t1 = x/55
t2 = (x+20)/40

x/55 + (x+20)/40 = 100/60
x = 1540/57

Total distance = x + (x+20) = 4220/57 miles = 74 2/57 miles

Solution:

41 years.

If the current age of Dakota is x
4(x+4) + 4(x+5) = 10x
Thus x=41 years

Solution:

The answer is 0.
As
6 / 7 = 42 but the answer is written as 2
3 / 9 = 27 but the answer is written as 7
8 / 2 = 16 but the answer is written as 6
If we look at the answers, the second digit has been used in the problem.
Now, as
4 / 5 = 20 and the second digit is 0, the answer is 0.

Solution:

200

To pass the exam ravish needs 40 + 40 = 80 marks.

=> (80/40) *100 = 200

Solution:

Winner = 300
Loser1 = 247
Loser2 = 221
Loser3 = 195


Explanation :

Loser1 = Winner- 53
Loser2 = Winner- 79
Loser3 = Winner- 105

Winner+ Winner- 53 + Winner- 79 + Winner- 105 = 963
4Winner= 1,200
Winner= 300

Loser1= 300 - 53
Loser1= 247

Loser2 = 300 - 79
Loser2 = 221

Loser3 = 300 - 105
Loser3 = 195

Answer: Winner= 300, Loser1= 247, Loser2 = 221, Loser3 = 195

Verify the ans
=> 300 + 247 + 221 + 195
=> 963
