If x = 3, and the first three terms of a proportion are (x+7x), (x+5), and (x+6), find the fourth proportional. यदि x = 3 है, और एक समानुपात के पहले तीन पद (x+7x), (x+5) और (x+6) हैं, तो चौथा समानुपाती ज्ञात कीजिए।
A
3 (3)
B
9 (9)
C
24 (24)
D
8 (8)

Correct Answer 3
Explanation
First term (a) = 8x = 24. Second term (b) = x+5 = 8. Third term (c) = x+6 = 9. Fourth proportional (d) = (b*c)/a = (8*9)/24 = 72/24 = 3.
