Question

what is the ratio of mean proportional between 4.8 and 10.8 and the third proportional to 0.4 and 2.4 ?

Answer 1

Dear Student,

◆ Answer -

x/y = 5

● Explaination -

Mean proportional of 4.8 and 10.8 is -

x = √(4.8 × 10.8)

x = √(51.84)

x = 7.2

Third proportional of 0.4 and 2.4 is -

y = 2.4² / 0.4

y = 5.76 / 0.4

y = 1.44

Ratio of x and y is -

x/y = 7.2 / 1.44

x/y = 5

Therefore, required ratio is 5.

Thanks dear...
