On celcius scale the temperature of body increases by 40∘C40^{\circ} \mathrm{C}. The increase in temperature on Fahrenheit scale is :

Options

  1. A68∘F68^{\circ} \mathrm{F}
  2. B75∘F75^{\circ} \mathrm{F}
  3. C72∘F72^{\circ} \mathrm{F}
  4. D70∘F70^{\circ} \mathrm{F}

Correct answer

C. 72∘F72^{\circ} \mathrm{F}

Step-by-step solution

We know that per ∘C{ }^{\circ} \mathrm{C} change is equivalent to 1.8∘1.8^{\circ} change in ∘F{ }^{\circ} \mathrm{F}. ∴40∘\therefore 40^{\circ} change on celcius scale will corresponds to 72∘72^{\circ} change on Fahrenheit scale. Hence option (3)
