If ‘A’ stands for ‘÷’, ‘B’ stands for ‘×’, ‘C’ stands for ‘+’ and ‘D’ stands for ‘−’, what will be come in place of question mark ‘?’ in the following equation? 3 B 41 A 3 D 34 C 17 = ?

A24

B26

C25

D22

Answer:

A. 24

Read Explanation:

let's solve this problem by substituting the given symbols with the corresponding mathematical operations and then evaluating the expression using the order of operations (PEMDAS/BODMAS).

1. Substitute the symbols:

The given equation is:

3 B 41 A 3 D 34 C 17 = ?

Substituting the symbols:

3 × 41 ÷ 3 − 34 + 17 = ?

2. Follow the order of operations (PEMDAS/BODMAS):

  • Parentheses / Brackets

  • Exponents / Orders

  • Multiplication and Division (from left to right)

  • Addition and Subtraction (from left to right)

3. Perform the calculations:

  • Multiplication: 3 × 41 = 123

    • The equation now is: 123 ÷ 3 − 34 + 17 = ?

  • Division: 123 ÷ 3 = 41

    • The equation now is: 41 − 34 + 17 = ?

  • Subtraction: 41 − 34 = 7

    • The equation now is: 7 + 17 = ?

  • Addition: 7 + 17 = 24

Therefore, the answer is 24

If 1 is added to each odd digit and 2 is subtracted from each even digit in the number 7318456, what will be the sum of the digits that are second from the left and second from the right in the new number thus formed?

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the set in which the numbers are related in the same way as are the numbers of the following sets. (Note: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
