Answer:
5. 2200 Loss; Loss Percent: 22%
6. TSA: 150 cm²; LSA: 150 cm²
7. 6400 bricks
8. Base: 35 unit²; Height: 42 unit²
Step-by-step explanation:
5.
Given,
Cost Price (CP): 10,000
Selling Price (SP): 8,000
Overhead Expenses: 200
To Find,
Loss and Loss Percentage.
Now,
CP<SP
Our Loss will be: 10,000-8,000+200=2,200
Loss Percentage will be: 100×Loss/CP =100×2,200/10,000 = 22%
Therefore,
Therefore,Loss: 2,200
Therefore,Loss: 2,200Loss Percentage: 22%
6.
Given,
Our Figure is Cube
Edge = 5cm
To Find,
TSA and LSA
TSA: 6×Side² = 6×5² = 6×5×5 = 150 cm²
LSA: 2×(lb+bh+hl) = [2×{(5×5)+(5×5)+(5×5)}] = 2(25+25+25) = 2(75) = 150 cm²
Therefore,
TSA: 150 cm²
LSA: 150 cm²
