Question 1 · Multiple choice

Question

Two apples weigh the same as five mandarins.

Bag X: 10 apples and 10 mandarins Bag Y: 4 apples and 25 mandarins Bag Z: 14 apples and 5 mandarins

Which statement is correct?

Options

  • A.All three bags weigh the same.
  • B.X and Y weigh the same; Z is different.
  • C.X and Z weigh the same; Y is different.
  • D.Y and Z weigh the same; X is different.
  • E.All three bags have different masses.

Correct answer

B.X and Y weigh the same; Z is different.

Explanation

Step 1: Create a common unit

We are told: 2 apples = 5 mandarins

Let 1 mandarin = 2 units (an arbitrary unit of weight).

Then 5 mandarins = 5 × 2 = 10 units.

Since 2 apples = 5 mandarins = 10 units:

1 apple = 10 ÷ 2 = 5 units

Step 2: Calculate the weight of each bag

Bag X: 10 apples + 10 mandarins

= 10 × 5 + 10 × 2 = 50 + 20 = 70 units

Bag Y: 4 apples + 25 mandarins

= 4 × 5 + 25 × 2 = 20 + 50 = 70 units

Bag Z: 14 apples + 5 mandarins

= 14 × 5 + 5 × 2 = 70 + 10 = 80 units

Step 3: Compare

BagWeight
X70 units
Y70 units
Z80 units

X and Y are equal; Z is heavier.

Answer: X and Y weigh the same; Z is different

Question 2 · Multiple choice

Question

A mother is currently 5 times as old as her daughter. Four years later, the mother will be 4 times as old as her daughter. How old is the daughter now?

Options

  • A.10
  • B.11
  • C.12
  • D.13
  • E.14

Correct answer

C.12

Explanation

Step 1: Write expressions for both ages now

Let daughter's age now = D

Mother's age now = 5D (5 times the daughter)

Step 2: Write the equation for 4 years' time

In 4 years:

  • Daughter = D + 4
  • Mother = 5D + 4

"Mother will be 4 times daughter's age":

5D + 4 = 4 × (D + 4)

5D + 4 = 4D + 16

D = 12

Step 3: Find mother's age now

Mother = 5 × 12 = 60 years old

Check: In 4 years: daughter = 16, mother = 64. Is 64 = 4 × 16? Yes ✓

Answer: The daughter is 12 years old now
