What was the original price?
A) $140
B) $150
C) $160
D) $180
Answer: C
Explanation: Let original price be x. 20% discount ⇒ price = x – 0.20x = 0.80x = $120. Thus x =
$120/0.80 = $150. (Oops, correction: $120/0.80 = $150, which matches option B.) **Correct

Explanation: Sugar : Flour = 3 : 5 ⇒ Sugar = (3/5)·Flour = (3/5)·12 = 36/5 = 7.2? Wait compute:
12*(3/5)=36/5=7.2, not among options. Re‑evaluate: maybe ratio means sugar:flour =3:5, so for
12 flour, sugar = (3/5)*12 = 7.2. None match; perhaps they meant flour:sugar =3:5, then sugar =
(5/3)*12 =20, also not. Let's adjust: Use 15 cups flour => sugar =9. But question as written
flawed. Let's replace with correct numbers.
