A) Rs.30
B) Rs.40
C) Rs.70
D) Rs.210
Correct Answer: B
Solution :
[b] \[\frac{A}{B}=\frac{3}{4};\,\,\frac{B}{C}=\frac{3.5}{3}=\frac{7}{6}\] \[and\,\,\,A+B+C=730\] \[\frac{3}{4}B+B+\frac{6}{7}B=730\] \[B\left( \frac{3}{4}+1+\frac{6}{7} \right)=730\] \[B=\frac{730\times 28}{73}=280\] \[C=\frac{6}{7}\times B=\frac{6}{7}\times 280=240\] .B exceeds that of C by \[(280-\,240)\] = Rs. 40You need to login to perform this action.
