Olympiad Test: Mathematical Operations - 1 - Question 1

If 'Q' stands for' added to; 'J' stands for 'multiplied by; T stands for' subtraction 'and 'P? stands for 'divided by' then 3 0 P 2 Q 3 J 6 T  5=?

Detailed Solution for Olympiad Test: Mathematical Operations - 1 - Question 1

Let's substitute the symbols with the actual mathematical operations:

  • P stands for division (÷)
  • Q stands for addition (+)
  • J stands for multiplication (×)
  • T stands for subtraction (−)

The expression is:

3 0 P 2 Q 3 J 6 T 53 

Now, substitute the symbols:

3 0 ÷ 2 + 3 × 6 − 5

Step-by-step:

  1. 0 ÷ 2 = 0
  2. 3 × 6 = 18
  3. 0 + 18 − 5 = 28

So, the final answer is 28.

Answer: Option B: 28

Olympiad Test: Mathematical Operations - 1 - Question 2

If P = 6, J = 4, L = 8 and M = 24, then M ÷ L × J + P=?

Detailed Solution for Olympiad Test: Mathematical Operations - 1 - Question 2

Let's substitute the given values into the expression:

Given:

  • P = 6
  • J = 4
  • L = 8
  • M = 24

The expression is:
M ÷ L × J + P

Substitute the values:
24 ÷ 8 × 4 + 6

Now, follow the order of operations (PEMDAS/BODMAS):

  1. 4 ÷ 8 = 32
  2. 3 × 4 = 12
  3. 12 + 6 = 18

So, the final result is 18.

Answer: Option D: 18
