  1. Calculate Area Formula: To find the base, use the formula for the area of a parallelogram: Area=base×height\text{Area} = \text{base} \times \text{height}.
  2. Rearrange for Base: Rearrange the formula to solve for the base: base=Areaheight\text{base} = \frac{\text{Area}}{\text{height}}.
  3. Plug in Values: Plug in the given values: base = 192 sq.cm÷24 cm.192 \, \text{sq.cm} \div 24 \, \text{cm}.
  4. Calculate Base: Calculate the base: base=8 cm.\text{base} = 8\,\text{cm}.
  5. Write in Standard Form: Standard form is written as a number between 11 and 1010 multiplied by a power of 1010.
  6. Calculate Percentage Increase: 1600016000 can be written as 1.6×1041.6 \times 10^4.
  7. Calculate Selling Price: Percentage increase = (New Value−Original ValueOriginal Value)×100%\left(\frac{\text{New Value} - \text{Original Value}}{\text{Original Value}}\right) \times 100\%.
  8. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)35]×100%[\frac{(50 - 35)}{35}] \times 100\%.
  9. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)÷35]×100%[(50 - 35) \div 35] \times 100\%.Calculate the increase: Percentage increase = (15÷35)×100%(15 \div 35) \times 100\%.
  10. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)÷35]×100%[(50 - 35) \div 35] \times 100\%.Calculate the increase: Percentage increase = (15÷35)×100%(15 \div 35) \times 100\%.Percentage increase = 0.42857...×100%0.42857... \times 100\%.
  11. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)÷35]×100%[(50 - 35) \div 35] \times 100\%.Calculate the increase: Percentage increase = (15÷35)×100%(15 \div 35) \times 100\%.Percentage increase = 0.42857...×100%0.42857... \times 100\%.Percentage increase = 42.857...%42.857...\%, which rounds to 42.86%42.86\%.
  12. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)÷35]×100%[(50 - 35) \div 35] \times 100\%.Calculate the increase: Percentage increase = (15÷35)×100%(15 \div 35) \times 100\%.Percentage increase = 0.42857...×100%0.42857... \times 100\%.Percentage increase = 42.857...%42.857...\%, which rounds to 42.86%42.86\%.Let the original cost price be xx. Then, selling price = cost price + profit.
  13. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)÷35]×100%[(50 - 35) \div 35] \times 100\%.Calculate the increase: Percentage increase = (15÷35)×100%(15 \div 35) \times 100\%.Percentage increase = 0.42857...×100%0.42857... \times 100\%.Percentage increase = 42.857...%42.857...\%, which rounds to 42.86%42.86\%.Let the original cost price be xx. Then, selling price = cost price + profit.Profit is 15%15\% of the cost price, so selling price = x+(15% of x)x + (15\% \text{ of } x).
  14. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)÷35]×100%[(50 - 35) \div 35] \times 100\%.Calculate the increase: Percentage increase = (15÷35)×100%(15 \div 35) \times 100\%.Percentage increase = 0.42857...×100%0.42857... \times 100\%.Percentage increase = 42.857...%42.857...\%, which rounds to 42.86%42.86\%.Let the original cost price be xx. Then, selling price = cost price + profit.Profit is 15%15\% of the cost price, so selling price = x+(15% of x)x + (15\% \text{ of } x).Selling price = x+(0.15x)=1.15xx + (0.15x) = 1.15x.
  15. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)÷35]×100%[(50 - 35) \div 35] \times 100\%.Calculate the increase: Percentage increase = (15÷35)×100%(15 \div 35) \times 100\%.Percentage increase = 0.42857...×100%0.42857... \times 100\%.Percentage increase = 42.857...%42.857...\%, which rounds to 42.86%42.86\%.Let the original cost price be xx. Then, selling price = cost price + profit.Profit is 15%15\% of the cost price, so selling price = x+(15% of x)x + (15\% \text{ of } x).Selling price = x+(0.15x)=1.15xx + (0.15x) = 1.15x.Plug in the selling price: 92=1.15x92 = 1.15x.
  16. Calculate Original Cost Price: Plug in the values: Percentage increase = [(50−35)35]×100%[\frac{(50 - 35)}{35}] \times 100\%.Calculate the increase: Percentage increase = (1535)×100%(\frac{15}{35}) \times 100\%.Percentage increase = 0.42857...×100%0.42857... \times 100\%.Percentage increase = 42.857...%42.857...\%, which rounds to 42.86%42.86\%.Let the original cost price be xx.
