If 20 - 10 means 200, 8 ÷ 4 means 12, 6 - 2 means 4, then 100 - 10 × 1000 ÷ 1000 + 100 × 10 =?

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

Given 20 - 10 = 200
but 20 × 10 = 200; - stands for ×.
Given 8 ÷ 4 = 12 but 8 + 4 = 12
∴ ÷ stands for +
Given 6 × 2 = 4 but 6 - 2 = 4
∴ × stands for -
Given expression
= 100 - 10 × 1000 ÷ 1000 + 100 × 10
= 100 × 10 - 1000 + 1000 ÷ 100 - 10
= 1000 - 1000 + 1000 ÷ 100 - 10
= 1000 - 1000 + 10 - 10
= 0 + 0 = 0

If + means -, - means ×, ÷ means + and + means ÷ then (3 - 5 ÷ 19) × 8 + 6 =?

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

Using correct symbols, we have
(3 × 15 + 19) ÷ 8 - 6
= (45 + 19) ÷ 8 - 6
= 64 ÷ 8 - 6 = 8 - 6 = 2

If P means division, T means addition, M means subtraction, and D means multiplication then what will be the value of expression 12M12D28P7T15?

Detailed Solution for Science Olympiad Test: Mathematical Operations - Question 3

12 M 12 D 28 P7 T 15
= 12 - 12 × 28 ÷ 7 + 15
= 12 - 12 × 4 + 15
= 12 - 48 + 15
= 27 - 48 = -21

If 36 × 92 = 9623, 25 × 82 = 8522, 68 × 75 = 7856 then 47 × 52 =?
Detailed Solution for Science Olympiad Test: Mathematical Operations - Question 4

The rule is the digits are jumbled in an order.
AB × CD = CBDA
36 × 92 = 9623
25 × 82 = 8522
68 × 75 = 7856
Similarly,
47 × 52 = 5724

If +  means minus, × means divided by, ÷ means plus, × means multiplied by then which of the following will be the value of expression 252 × 9 - 5 + 32 ÷ 92?
Detailed Solution for Science Olympiad Test: Mathematical Operations - Question 6

252 × 9 - 5 + 32 ÷ 92
= 252 ÷ 9 × 5 - 32 + 92
= 28 × 5 - 32 + 92
= 140 - 32 + 92 = 232 - 32 = 200
