A) 20
B) 33.1
C) 44.2
D) 100
Correct Answer: B
Solution :
Volume of the cone \[=\frac{1}{3}\pi {{r}^{2}}h\] Effective change of 10% and 10% \[=\left( 10+10+\frac{10+10}{100} \right)%=21%\] Effective change of 21 % and 10% \[=\left( 21+10+\frac{21\times 10}{100} \right)%=33.1%\]You need to login to perform this action.
