Three (3) separate overcast layers exist with bases at 2,500, 7,500 and 9,000 feet.✓ Correct Answer
The top of the lower overcast is 2,500 feet; base and top of second overcast layer are 4,500 and 9,000 feet, respectively.
The base of the second overcast layer is 2,500 feet; top of second overcast layer is 7,500 feet; base of third layer is 9,000 feet.
Explanation
In a PIREP the sky-cover group reads base, amount, top, in hundreds of feet MSL, with layers separated by slashes. 025 OVC 045 is an overcast layer from 2,500 to 4,500 feet, 075 OVC 080 one from 7,500 to 8,000 feet, and 090 OVC a third with its base at 9,000 feet, so there are three overcast layers with bases at 2,500, 7,500 and 9,000 feet.
