   • A10 + 5 - 14 ÷ 10 * 15 = 158
   • B30 + 5 + 14 - 10 * 15 = 122
   • C30 - 5 + 14 ÷ 10 * 15 = 162
   • D30 * 5 - 4 ÷ 10 + 15 = 31✓
   • ENone of these

   Explanation

   Your equation is:10 + 5 - 14 ÷ 10 * 15 = 158First, replace the symbols:+ → -- → +÷ → ** → ÷Thus, the equation becomes:10 - 5 + 14 * 10 ÷ 15Now, solve step-by-step following BODMAS:Multiplication and Division first:14 * 10 = 140140 ÷ 15 ≈ 9.333...Now the equation becomes:10 - 5 + 9.333...Left to right (Addition/Subtraction):10 - 5 = 55 + 9.333... = 14.333...Thus:Final result: 14.333..

    If 7(x-2) = 3x - 2. What is the value of x?

    • A-4
    • B-3
    • C2
    • D3✓
    • E4

    Explanation

    To solve the equation 7(x-2) = 3x - 2, begin by expanding the left side: 7x - 14 = 3x - 2. Next, move all terms involving x to one side and constant terms to the other: 7x - 3x = -2 + 14. Simplify to get 4x = 12. Divide both sides by 4 to find x = 3.Options A, B, C, and E result in incorrect equations when substituted back into the original equation, hence they are incorrect.

    Read the following and choose the correct answer: "X, Y and Z are three whole numbers less than 31 but greater than 23. X is a prime number. Y is the largest odd number smaller than 35. Z is the smallest even number?

    • AX is 31, Y is 29 and Z is 24.
    • BX is 29, Y is 29 and Z is 24.✓
    • CX is 23, Y is 29 and Z is 24.
    • DX is 27, Y is 31 and Z is 26.

    Explanation

    Let's analyze the given information: X is a prime number. Y is the largest odd number smaller than 35. Z is the smallest even number. Now, let's find suitable values for X, Y, and Z based on these conditions: X is a prime number. Prime numbers between 23 and 31 are 23, 29, and 31. So, X could be any of these. Y is the largest odd number smaller than 35. The largest odd number smaller than 35 is 33. Z is the smallest even number. The smallest even number is 24. The correct option that satisfies all conditions is: B. X is 29, Y is 33, and Z is 24.

    Read the following and choose the correct answer.X, Y and Z are three whole numbers less than 24 but greater than 11. X is the smallest prime number. Y is the largest number divisible by 3. Z is the smallest number divisible by 11.

    • AX is 13, Y is 24, Z is 11
    • BX is 13, Y is 21, Z is 22✓
    • CX is 11, Y is 21, Z is 11
    • DX is 11, Y is 24, Z is 22

    Explanation

    As the question states, the whole number is less than 24, hence options A and D are eliminated. Let's list the numbers in question, 12,13,14,15,16,17,18,19,20,21,22,23. X is the smallest prime number. Among the numbers listed 13 is the smallest prime number so X is 13. Y is the biggest number divisible by 3. 21 is the largest number among these but it is divisible by 3. So Y is 21. Z is the number divisible by 11. Amongst all these numbers only 22 is divisible by 11. This is what makes option B the most appropriate choice.

    Each problem consists of three statements. Based on the first two statements, the third statement may be true, false, or uncertain.Blueberries cost more than strawberries.Blueberries cost less than raspberries.Raspberries cost more than both strawberries and blueberries.If the first two statements are true, the third statement is:

    • ATrue✓
    • BFalse

    • DNone of these
    • ENone of these

    Explanation

    The first two statements provide a clear hierarchy of fruit prices: blueberries are more expensive than strawberries, and raspberries are more expensive than blueberries. Therefore, raspberries must be more expensive than both strawberries and blueberries, making the third statement true. Option A is correct as it accurately reflects this deduction. Options B and C are incorrect because the cost relationships provided lead to a definite conclusion about the third statement. Option D is also incorrect as it suggests there is no correct option, which contradicts the evidence given.
