Detailed Solution
Download Solution PDFGiven:
First number = (1/3)rd of 27 = 9
Second number = (4/5)th of 30 = 24
Third number = (3/7)th of 35 = 15
Formula used:
If a, b, c, and d are in proportion, then a/b = c/d
Calculation:
We need to find the fourth proportion (d).
⇒ 9/24 = 15/d
⇒ d = (24 × 15)/9
⇒ d = 360/9
⇒ d = 40
∴ The correct answer is option 2.
