Step-by-step explanation:
Statisticians use two-way tables and segmented bar charts to examine the relationship between two categorical variables.
Area of triangle=1/2bh
Area=248ft
Base=x
Height=2x-1
248=1/2×x×(2x-1)........
Answer: 10%
Step-by-step explanation:
Since the shopkeeper purchased 60 pencil boxes for 4,500, he purchased them at the rate of:
= 4500 / 60
= 85 per pencil box
If the shopkeeper sold them at the rate of 4,125 for 50 pencil boxes, then he sold them at the rate of:
= 4125 / 50
= 82.50 per pencil box.
Therefore the percentage profit will be:
= Gain / Cost price × 100
= (82.50 - 75) / 75 × 100
= 7.5/75 × 100
= 10%
