Step-by-step explanation:
Given cost of ten scarfs is 25 .
let the cost of one scarf be x.
Cost of scars increases with number of scarfs. Hence, They are directly proportional [ \frac{ x_{1}}{ x_{2} } = \frac{ y_{1}}{ y_{2} }x2x1=y2y1 ]
10/1 = 25/x
10x = 25
x = 25/10 = 5/2 = 2.5 .
Therefore, One scarf costs 2.5 rupees or 5/2 rupees
