A. 9
B. 24
C. 6
D. 16
Step-by-step explanation:
Given ratios are;
A. 2 : 3 = 6 : x

B. 4 : 7 = x : 42
Product of mean = Product of extreme

Dividing both sides by 7

C. 2x : 48 = 3 : 12
Product of extreme = Product of mean

Dividing both sides by 24

D. 12 : 15 = x : 20
Product of mean = Product of extreme

Dividing both sides by 15
