Correct answer is C
Where the loss= (100-15)%
= 85%
Ratio = 85:100 or 17:20
If the equations x2 - 5x + 6 = 0 and x + px + 6 = 0 have the same roots, find the value of p.
5
6
-5
-6
Correct answer is C
If "x" is the same for both equations, then they are equivalent.
(i.e., the equations have same roots), then the equations are equivalent.
Then p = -5
The straight line y = mx - 4 passes through the point(-4,16). Calculate the gradient of the line
-5
-3
3
5
Correct answer is A
where x=-4 and y = 16,
16 = -4m - 4
4m = -16 - 4
4m = -20
M = -5
The mean of two numbers x and y is 4. Find the mean of four numbers x, 2x, y and 2y
2
4
6
8
Correct answer is C
Since the mean of the two numbers x and y is:
x+y2 = 4
x+y =2 * 4
x+y = 8
then we get:
x+2x+y+2y4
=(3x+3y4)
= 3(x+y4) → 3(84)
= 3 * 2
= 6
A rectangle with width 34cm and area 3 38cm2. Find the length
6cm
412cm
2 58cm
12cm
Correct answer is B
The area of a rectangle = length ✕ width
: Length = area ÷ width → 3 38 ÷ 34
= 278 * 43
= 412cm
