Answer:
p = 60
Step-by-step explanation:
This relationship is called 'continued proportion' and the rule which is applied is THE PRODUCT OF MEANS = THE PRODUCT OF EXTREMES. The means are the two middle numbers and the extremes are the 2 numbers at the end. That means, the means are 40 and 45, the extremes are 30 and p.
= 40 x 45 = 30p
= 1800 = 30p
= 1800 / 30 = p
∴ p = 60
