Q. |
The average temperature on Wednesday, Thursday and Friday was $25^circ$. The average temperature on Thursday, Friday and Saturday was $24^circ$. If the temperature on Saturday was $27^circ$, what was the temperature on Wednesday? |

✖ A. |
$24^\circ$ |

✖ B. |
$21^\circ$ |

✖ C. |
$27^\circ$ |

✔ D. |
$30^\circ$ |

**Solution:**

Option(**D**) is correct

Total temperature on Wednesday, Thursday and Friday was $25×3=75^\circ$

Total temperature on Thursday, Friday and Saturday was $24\times 3=72^\circ$

Hence, difference between the temperature on Wednesday and Saturday= $3^\circ$

If Saturday temperature =$27^\circ$, then Wednesday's temperature =$27^\circ+3^\circ=30^\circ$

here's my take:

we'll form two equations

Wed + Thur + Fri $=25*3=75$

Thur + Fri + Sat $=24*3=72$

Subtract the two equations ,we get

Wed - Sat $=3$

Wed = 3 + Sat $=3+27=\textbf{30}$

Awesome, just love it...
