  • A
    ${D_7} = l + \frac{{\left( {\frac{N}{7} - C} \right)}}{f} \times i$
  • B
    ${D_7} = l + \frac{{\left( {\frac{N}{{10}} - C} \right)}}{f} \times i$
  • ${D_7} = l + \frac{{\left( {\frac{{7N}}{{10}} - C} \right)}}{f} \times i$
  • D
    ${D_7} = l + \frac{{\left( {\frac{{10N}}{7} - C} \right)}}{f} \times i$
