Correct Answer: 5.5
The first 10 natural numbers sum to 55, and 55 ÷ 10 = 5.5.
Correct Answer: 5
(2 + 4 + 6 + 8) ÷ 4 = 20 ÷ 4 = 5.
Correct Answer: 10
(5 + 10 + 15) ÷ 3 = 30 ÷ 3 = 10.
Correct Answer: 8
(4 + 8 + 12) ÷ 3 = 24 ÷ 3 = 8.

7 solved MCQs shown directly below
Correct Answer: 320
If 25% of the number is 80, the number is 80 × 100 ÷ 25 = 320.
Correct Answer: 25%
15 ÷ 60 × 100 = 25%.
Correct Answer: 75%
3 ÷ 4 × 100 = 75%.
Correct Answer: 50
20% of 250 = 250 × 20 ÷ 100 = 50.
Correct Answer: 5%
10 ÷ 200 × 100 = 5%.
Correct Answer: 90
45% of 200 = 200 × 45 ÷ 100 = 90.
Correct Answer: 240
20% of 200 is 40, so 200 + 40 = 240.

Correct Answer: 0.6
3 ÷ 5 = 0.6.
Correct Answer: 35
a:b = 4:7 with a = 20 gives b = 20 × 7 ÷ 4 = 35.
Correct Answer: 10
x:y = 2:3 with total 25 gives x = 25 × 2 ÷ 5 = 10.
Correct Answer: 10:3
a:b = 5:4 and b:c = 8:3 give a:c = 40:12 = 10:3.

2 solved MCQs shown directly below
Correct Answer: 200
Simple interest = 1000 × 10% × 2 = Rs. 200.
Correct Answer: 20%
Doubling at simple interest means interest equals the principal, so rate = 100 ÷ 5 = 20% per year.

6 solved MCQs shown directly below
Correct Answer: 40
Area of a rectangle = length × width = 8 × 5 = 40.
Correct Answer: 24
Perimeter of a square = 4 × side = 4 × 6 = 24 cm.
Correct Answer: πr²
The area of a circle is πr²; 2πr is its circumference.
Correct Answer: 81
Area of a square = side² = 9² = 81.
Correct Answer: Double
Area = length × width, so doubling the length doubles the area.
Correct Answer: Four times
Area depends on r², so doubling the radius multiplies the area by 2² = 4.

Correct Answer: 60 km/h
Speed = distance ÷ time = 120 ÷ 2 = 60 km/h.
Correct Answer: 40 km/h
Speed = 60 ÷ 1.5 = 40 km/h.
Correct Answer: 5 km/h
Speed = 30 ÷ 6 = 5 km/h.
Correct Answer: 48
For equal distances, average speed = 2 × 40 × 60 ÷ (40 + 60) = 48 km/h.
Correct Answer: 0
An object at rest covers no distance.
Correct Answer: Distance ÷ Time
Average speed = total distance ÷ total time.

No. It is a Sir Adnan mock test headed 'PMS GK Basic Mathematics Mock Test', prepared for PMS Screening 2026. It is published as paperType 'mock', never as a past paper, and the year 2026 is the booklet's mock label, not a claimed exam session.
Printed Q59 (mean of the first 10 natural numbers) is the same question as printed Q1 (average of the first 10 natural numbers), so it is cross-linked to Q1 and not published twice. Every other printed item is published, with four booklet keys corrected to the standard answer and flagged.
Q27 (10 days after Monday is Thursday, not Friday), Q82 (mean of 4, 8, 12 is 8, not 10), Q86 (15 days after Friday is Saturday, not Monday) and Q100 (100 ÷ 4 × 5 = 125, not 100). Each correction is flagged in the item's keyFlag.
