Question

Geometric mean of 2 numbers is 15. If by mistake one figure is taken as 5 instead of 3,
find the corrected geometric mean.
​

Answer 1

Step-by-step explanation:

√ab = 15

ab = 225

(1) When a = 5

then b = 225/5 = 45

(2) when a = 3 & b = 45

Then correct geometric mean

G.M. = √3*45 = √135 = 3√15
