A) Rs. 720
B) Rs. 600
C) Rs. 800
D) Rs. 880
Correct Answer: C
Solution :
[c] Let the man at first had Rs. x Money lost by man = 12.5 of x \[=\frac{25}{2}\times \frac{1}{100}\times x=\frac{x}{8}\] \[\therefore \] Remaining money \[=x-\frac{x}{8}=\frac{7x}{8}\] Money spent = 70% of \[\frac{7x}{8}\] \[=\frac{70}{100}\times \frac{7x}{8}=\frac{49}{80}x\] Money left with man \[=\frac{7x}{8}-\frac{49}{80}x=\frac{21}{80}x\] According to question Money left \[=\frac{21}{80}x=210\] \[\Rightarrow \] \[x=\frac{210\times 80}{21}=800\] \[\therefore \] At first man had Rs. 800.
