Correct Answer: B
Solution :
(b): Let no. s be \[2x,3x,4x\] \[{{\left( 2x \right)}^{3}}+{{\left( 3x \right)}^{3}}+{{\left( 4x \right)}^{3}}\] \[=\left( 8+27+64 \right){{x}^{3}}\] \[=99{{x}^{3}}\] Also, \[99{{x}^{3}}=33957\] \[{{x}^{3}}=343\] \[x=7\] Nos are \[2\times 7,3\times 7,4\times 7.\]You need to login to perform this action.
