A) 36
B) 63
C) 67
D) 37
Correct Answer: B
Solution :
Let the required number be x. According to question, \[x\left( 2\frac{1}{3}x \right)-61=9200\] \[\Rightarrow \frac{7}{3}{{x}^{2}}-61=9200\Rightarrow \frac{7}{3}{{x}^{2}}=9261\] \[\Rightarrow {{x}^{2}}=\frac{9261\times 3}{7}\Rightarrow x=\sqrt{3969}\Rightarrow x=63\]You need to login to perform this action.
