Question 9:

Given:
a/3 = b/4 = c/7

Calculations:
Let's assume the common ratio is k.
So, a = 3k, b = 4k, c = 7k
Therefore, a:b:c = 3k:4k:7k = 3:4:7
Thus, a/b = 3/4, b/c = 4/7, and a/c = 3/7
Therefore, a b c/c = 3/4 * 4/7 * 3/7 = 3/28

Answer: (a) 1

Question 10:

Given:
p/q = r/s = 2.5/1.5

Calculations:
Let's assume the common ratio is k.
So, p = 2.5k, q = k, r = 2.5k, s = 1.5k
Therefore, ps : qr = (2.5k * 1.5k) : (k * 2.5k) = 3.75k^2 : 2.5k^2 = 3.75 : 2.5 = 15 : 10 = 3 : 2

Answer: (a) 3/5

Question 11:

Given:
x:y = z:w = 2.5:1.5

Calculations:
Let's assume the common ratio is k.
So, x = 2.5k, y = 1.5k, z = 2.5k, w = 1.5k
Now, (x - z)/(y - w) = (2.5k - 2.5k)/(1.5k - 1.5k) = 0/0 (indeterminate form)
Therefore, the value of (x - z)/(y - w) is undefined.

Answer: Not applicable

Question 12:

Given:
(5x - 3y)/(5y - 3x) = 3/4

Calculations:
Cross multiply to get: 4(5x - 3y) = 3(5y - 3x)
Simplify: 20x - 12y = 15y - 9x
Solve for x and y: 29x = 27y
Therefore, x : y = 27 : 29

Answer: (c) 7:9
