You can solve the question using simultaneous equation.
Kamil gave Kuhan RM15 : a - 15
They have the same amount of money : (a + b)/2
Equation 1 : a - 15 = (a + b)/2

Kuhan gave Kamil RM25 : b - 25
Kamil have as much as Kuhan left : 2(2b - 25) <-- Kamil's money
Equation 2 : b - 25 = (a + b) - 2(2b - 25)
(a + b) - 2(2b - 25) is Kuhan's money.

Equation 1 : Express a in terms of b.
2a - 30 = a + b
a = 30 + b

Substitute it into Equation 2.
b - 25 = (30 +b + b) - 2(b - 25)
b = RM 105

a = 30 + 105
a = RM 135

For life's sake, lets prove the values are correct.

Kamil gave RM15 and then they have the same amount of money.
135 - 15 = RM 120
Total money : 105 +135 = RM 240
Then, 120 + 120 should be RM 240
120 + 120 = RM 240
Proven!

Next.
Kuhan gave RM 25 and Kamil have twice as much as Kuhan left.
105 - 25 = RM 80 <-- Kuhan's money
Kamil's money is 2(Kuhan's money)
Kuhan's money + 2(Kuhan's money) should be RM 240.
80 + 2(80) = RM 240
Proven!
Yay :D
