Explanation
By combining both statements, we can make some deductions. Let's assume the monthly salary of B is X.
According to Statement I, B gets 10% less than C, which means B's salary is 90% of C's salary:
B's salary = 0.9 * C's salary
B's salary = 0.9 * Rs. 2500
B's salary = Rs. 2250
According to Statement I, A gets 15% more than B, which means A's salary is 115% of B's salary:
A's salary = 1.15 * B's salary
A's salary = 1.15 * Rs. 2250
A's salary = Rs. 2587.50
Based on the given information, the monthly salary of A is approximately Rs. 2587.50. i.e A. Rs. 2587.5
