Question

The 1st,3rdand 4thterms of a proportion are57,51 and 85 respectively. Find the 2nd term of the proportion.

Answer 1

Step-by-step explanation:

let the second term of the proportion be x:-

→ 57 : x :: 51 : 85

→ 57/x = 51/85

→ 57/x = 3/5

• Now, cross multiply it:-

→ 3x = 57×5

→ x = (57×5)/3

→ x = 19×5

→ x = 95

Therefore, the 2nd term of proportion is 95.
