What is the ratio of the mean proportional between 1.2 and 10.8 to the third proportional to 0.2 and 1.2?
Answer & explanation
Correct answer: option 2
Mean Proportional = \(\sqrt {1.2 × 10.8 }\)
⇒ MP = 0.36
⇒ The third proportional x,
⇒ 0.2x = 1.2 x 1.2
⇒ 0.2x = 1.44
⇒ x = 0.72
⇒ MP : TP = 0.36 : 0.72 = 1 : 2.
