Explanation

Set up a cross-multiplying diagram and complete it with the information provided:

Cups of Sugar\(\frac{3}{2}\)x
Cookies2430


Solve for x:

(3/2)(30) = (24)(x) → 45 = 24x → 1.875 = x

Compare the quantities:

Quantity A: 1.875 cups
Quantity B: 2 cups

Hence Option B is greater.

Thus, column B should be 2 instead of 12, right?

The amount of sugar required for the same recipe to make 30 cookies

A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.


GIVEN: For every 3/2 cups of sugar, we get 24 cookies

We can solve this question with equivalent ratios

We're comparing cups of sugar with number of cookies.
Let x = the cups of sugar required to make 30 cookies

We get: (3/2)/24 = (x)/30
Cross multiply to get: (24)(x) = (3/2)(30)
Simplify: 24x = 45
Solve: x = 45/24

ASIDE: Since 48/24 = 2, we know that 45/24 is less than 2

We get:
QUANTITY A: some number less than 2
QUANTITY B: 2

Answer: B

1
1.5 Cups of sugar for cookies 24 (given)
0.5 Cups of sugar for cookies 8 (dividing by 3)
2 Cups of sugar for cookies 32 (multiply by 4)

By using 4 cup of sugar, producible cookies are 32
so to produce 30 cookies, required cup of sugar is less than 2.

so ans is B
