The juice stall at the circus stocked just 2 brands of orange juice tetra packs. Brand A costs $1 per pack and brand B costs $1.5 per pack. Last week , brand A contributed to p% of stall’s revenue and accounted for q% of sales of juice tetra packs. Which of the following expresses p in terms of q?	Choose one.
A) 100q/(150 – q)	B) 200q/(250-q)	C) 200q/(300-q)	D) 250q/(400-q)	E) 300q/(500-q)
1. Let the number of units sold be 100. Then q units of A are sold and (100-q ) units of B are sold.   Total revenue= Revenue due to A + Revenue due to B   = (No.of units of A sold * Cost/unit of A) + (No.of units of B sold * cost/unit of B)   = q *1 + (100-q ) *1.5   = q + (150-1.5q ) --- (1)   2. But we know, revenue due to A = p%. of the total revenue --- (2)   3. To express p in terms of q we need to relate (1) and (2)   4. p% = q / ( q + (150-1.5q ))   200q/(300-q)   or m= 100n / 150-0.5n = 200n/(300-n)
