Answer: Let's say Trisha is currently T years old and Mina is currently M years old.
We know from the problem statement that Trisha is twice as old as Mina:
T = 2M
We also know that 10 years from now, Trisha will be 4 years older than Mina:
T + 10 = M + 4
We can substitute the first equation into the second equation:
2M + 10 = M + 4
We can then solve for M:
M = 6
So, Mina is currently 6 years old.
We can use the first equation to find Trisha's current age:
T = 2M = 2 * 6 = 12
Therefore, Trisha is currently 12 years old and Mina is currently 6 years old.
