A sales boy is allowed \(4\frac12\) % discount on the total sales made by him plus a bonus of \(\frac14\) % on the sales over Rs.12,000.If his total earnings were Rs.2400, then his total sales(in Rs.) are ?
Solution
Correct Answer: Option D
Let the total earnings be Rs.x
Then \(4\frac12\) % of x + \(\frac14\)% of (x-12000) =2400
\(\Rightarrow\frac92\times\frac x{100}+\frac14\times\frac{x-12000}{100}=2400\)
=> x=50,589.47
