A) \[9\frac{1}{11}%\]
B) \[10\frac{1}{11}%\]
C) 11%
D) 10%
Correct Answer: A
Solution :
| Let 5's income be Rs. 100. |
| \[\therefore \]A's income = Rs. 110 |
| If A's income is Rs. 110. |
| B's income = Rs. 100 |
| If A's income is Rs. 100. |
| B's income = Rs. \[\left( \frac{100}{110}\times 100 \right)\]= Rs. \[\frac{1000}{11}\] |
| \[\therefore \]B's income is less than A's income by |
| \[\left( 100-\frac{1000}{11} \right)%=\frac{100}{11}%=9\frac{1}{11}%\] |
