MCQ
On centigrade scale the temperature of a body increases by $30$ degrees. The increase in temperature on Fahrenheit scale is
- A$50^{\circ}$
- B$40^{\circ}$
- C$30^{\circ}$
- ✓$54^{\circ}$
✓
Answer
Correct option: D.
$54^{\circ}$
(d) Difference of $100^{\circ} \mathrm{C}=$ difference of $180^{\circ} \mathrm{F}$
$\therefore$ Difference of $30^{\circ}=\frac{180}{100} \times 30=54^{\circ}$
$\therefore$ Difference of $30^{\circ}=\frac{180}{100} \times 30=54^{\circ}$
