Answer:
Present age of Dianna is 45 years old
Explanation:
Let "x" be the present age of Dianna
Given that, In 3 years, Dianna will be 4 times as old as she was 33 years ago
Then: In three years time Diana’s age would be x + 3
And: thirty three years ago it would have been x - 33
From given question,
x + 3 = 4 times as old as she was 33 years ago
x + 3 = 4(x - 33)
x + 3 = 4x - 132
x - 4x = -132 - 3
-3x = -135
x = 45
Thus present age of Dianna is 45 years old
