Rajesh gets a commission at 10% on cash sales and 8% on credit sales. If he receives ₹ 4,400 as commission on the total sales of ₹ 50,000, find the sales made by him on cash and on credit sales.Solution:Let cash sales be ₹ \(x\)\(\therefore\) Credit…

Answer: Boxes: \(50{,}000-x\); 4,400; 20,000; 2,400. Cash sales ₹ 20,000 and credit sales ₹ 30,000.

Credit sales \(=\)₹ \(\boxed{50{,}000-x}\).

\(\boxed{4{,}400}=\frac{10x}{100}+\frac{8(50000-x)}{100}\Rightarrow 440000=10x+400000-8x\Rightarrow 2x=40000\Rightarrow x=\boxed{20{,}000}\).

So cash sales are ₹ 20,000 and credit sales are ₹ 30,000. Commission on cash sales \(=\)₹ 2,000 and commission on credit sales \(=\frac{8}{100}\times 30000=\)₹ \(\boxed{2{,}400}\) (total ₹ 4,400).

(The printed last line reads “Commission on cash sales is ₹ 20,000 and on credit sales is ₹ [ ]”. ₹ 20,000 is really the cash sales figure, so if the line is read as “cash sales … credit sales”, the last box is ₹ 30,000; read as printed (commission on credit sales), it is ₹ 2,400.)
