Q. If the total sales for all products in Q1 is $6000, what is the sales for Product D?
A.
$1000
B.
$2000
C.
$3000
D.
$4000
Solution
Total sales for Q1 is $6000. Given sales for Products A, B, and C are $2000, $2000, and $2000 respectively, Product D must be $6000 - ($2000 + $2000 + $2000) = $1000.
Q. If two cars are moving in the same direction at speeds of 60 km/h and 80 km/h, how long will it take for the faster car to overtake the slower car if they start 100 km apart?
A.
1 hour
B.
1.5 hours
C.
2 hours
D.
2.5 hours
Solution
Relative speed = 80 km/h - 60 km/h = 20 km/h. Time = Distance / Speed = 100 km / 20 km/h = 5 hours.
Q. If two chords intersect inside a circle and the lengths of the segments are 3 cm and 4 cm for one chord, and 2 cm and x cm for the other, what is the value of x?
A.
5
B.
6
C.
7
D.
8
Solution
Using the intersecting chords theorem: 3 * 4 = 2 * x, so 12 = 2x, thus x = 6.
Q. If two chords intersect inside a circle, and the lengths of the segments of one chord are 4 cm and 6 cm, what is the length of the other chord if its segments are x cm and y cm?
A.
10
B.
12
C.
14
D.
16
Solution
Using the intersecting chords theorem: 4 * 6 = x * y. If x + y = 10, then x = 4 and y = 6.
Q. If two tangents are drawn from a point outside a circle, and the lengths of the tangents are 7 cm and 7 cm, what is the distance from the point to the center of the circle?
A.
7√2
B.
7
C.
14
D.
10
Solution
The distance from the point to the center is equal to the length of the tangent divided by cos(45°), which is 7√2.
Q. If two tangents are drawn from a point outside a circle, and the lengths of the tangents are 7 cm each, what is the distance from the point to the center of the circle?
A.
7√2
B.
7
C.
14
D.
√49
Solution
The distance from the point to the center is given by the formula: distance = √(tangent length² + radius²). Here, radius = 7, so distance = √(7² + 7²) = √(49 + 49) = √98 = 7√2.
