Asked in Maths and Science Reasoning Mock

What number is covered by the flower?

Correct answer: D. 4

  • A. 1
  • B. 2
  • C. 3
  • D. 4

Explanation

To solve this problem, assign variables to each symbol: let circles = a, triangles = b, and squares = c.First, solve the equation with triangles: 2b = 4, so b = 2.Next, solve for circles using the equation a + b = 3: a + 2 = 3, thus a = 1.Then, find squares using b + c = 5: 2 + c = 5, so c = 3.Finally, solve for the flower using a + c: 1 + 3 = 4. Therefore, the flower covers the number 4.Options 1, 2, and 3 do not satisfy these conditions and do not complete the equation accurately.
