Question

The first, second and fourth terms of a proportion are 5.2, 3.9, and 3 respectively. Find ito third term

Answer 1

Step-by-step explanation:

It is given that the terms in the proportion are,

The first term = 22

The second term = 33

The third term = 50

Let the fourth term be “x”.

For the given proportion 22:33::50:x, we have

[Product of extremes] = [Product of means]

⇒ [First term * Fourth term] = [Second term * Third term]

⇒ [22 * x] = [33 * 50]

⇒ x = [33 * 50] / [22]

⇒ x = 75
