If '+' means 'minus', '-' means 'multiply', '÷' means 'plus' and 'x' means 'divide', then 10 x 5 ÷ 3 - 2 + 3 = ?

Detailed Solution for MCQ: Mathematical Operations- 1 - Question 1

? = 10 x 5 ÷ 3 - 2 + 3
= 10 ÷ 5 + 3 x 2 - 3
Apply the rule BODMAS
Do things in Brackets First
(Powers, Roots) before Multiply, Divide, Add or Subtract.
Multiply or Divide before you Add or Subtract
= 10 ÷ 5 + 3 x 2 - 3
= 2 + 3 x 2 - 3
Addition
= 2 + 6 - 3
Subtraction
= 8 - 3 = 5

MCQ: Mathematical Operations- 1 - Question 3
Save

Select the correct combination of mathematical signs to replace the * signs and to balance the given equation.
40 * 2 * 4 * 3 * 8

Detailed Solution for MCQ: Mathematical Operations- 1 - Question 3

Given, 40* 2* 4 * 3 * 8
Let us check all the options one by one.
From option (a), putting the signs in given equation, we get
40 + 2 - 4 ÷ 3
= 8 ⇒ 42 - 4/3 = 8
⇒ 126 - 4 = 24 ⇒ 122 = 24
∴ L H S ≠ R H S
So, option (a) is incorrect.
From option (b), putting the signs in given equation, we get
40 ÷ 2 + 4 = 3 x 8
⇒ 20 + 4 = 24 ⇒ 24 = 24
LHS = RHS
Hence, option (b) is correct and there is no need to check remaining options.

MCQ: Mathematical Operations- 1 - Question 4
Save

Direction: In each of the following questions, all the equations except one have been solved according to a certain rule. You are required to solve the unsolved equation following the same rule and to choose the correct answer out of the given options.

4 - 4 = 17, 6 - 6 = 37, 2 - 2 = 5, 5 - 5 = ?
Detailed Solution for MCQ: Mathematical Operations- 1 - Question 4

As, 4 - 4 ⇒ 4 x 4 + 1 = 17
6 - 6 ⇒ 6 x 6 + 1 = 37
2 - 2 ⇒ 2 x 2 + 1 = 5
Similarly, 5 - 5 ⇒ 5 x 5 + 1 = 26
∴ ? = 26

MCQ: Mathematical Operations- 1 - Question 5
Save

If S means '-', Q means 'x' , R means '÷' and P means '+' then
1   P   45   R   2   Q   2   S   4 = ?
Detailed Solution for MCQ: Mathematical Operations- 1 - Question 5

After replacing the sign according to question
1   P   45   R   2   Q   2   S   4
Apply the BODMAS Rule
= 1 + 45 ÷ 2 x 2 - 4
= 1 + 22.5 x 2 - 4
= 1 + 45 - 4 = 42

MCQ: Mathematical Operations- 1 - Question 6
Save

If '@' means 'x', 'c' means '÷' % means (+) and '$' means '-', then 6%12C3@8   $   3 = ?
Detailed Solution for MCQ: Mathematical Operations- 1 - Question 6

∵ 6%12C3@8   $   3 = ?
After replacing the sign according to the question
⇒ 6 + 12 ÷ 3 x 8 - 3 = ?
Apply the BODMAS Rule
⇒ 6 + 4 x 8 - 3 = ?
⇒ 6 + 32 - 3 = ?
⇒ 38 - 3 = ?
∴ ? = 35

MCQ: Mathematical Operations- 1 - Question 7
Save

Direction: What should be the correct signs to balance the following equations ?

6   5   4 = 34
Detailed Solution for MCQ: Mathematical Operations- 1 - Question 7

Let us check all the options one by one.
From option (a),
6 - 5 + 4 = 34 (using VBODMAS rule)
⇒ 10 - 5 = 34 ⇒ 5 = 34
∴ LHS ≠ RHS
So, option (a) is incorrect
From option (b),
6 x 5 + 4 = 34 (using VBODMAS rule)
⇒ 30 + 4 = 34 ⇒ 34 = 34
⇒ LHS = RHS
So, option (b) gives us the correct answer and hence, there is no need to check remaining options.

MCQ: Mathematical Operations- 1 - Question 8
Save

Direction: What should be the correct signs to balance the following equations ?

65 40 11 = 36
Detailed Solution for MCQ: Mathematical Operations- 1 - Question 8

Let us check all the options one by one.
From option (a),
65 - 40 + 11 = 36 ⇒ 76 - 40 = 36
⇒ 36 = 36 ⇒ LHS = RHS
So, option (a) is correct and hence there is no need to check remaining options.

MCQ: Mathematical Operations- 1 - Question 9
Save

Which sequence of mathematical symbols can replace *in the given equation to balance the equation ?
7 * 7 * 2 * 1 = 12
Detailed Solution for MCQ: Mathematical Operations- 1 - Question 9

Given, 7 * 7 * 2 * 1 = 12
Let us check all the options one by one.
From option (a), putting the signs in given equation, we get
7 x 7 - 2 ÷ 1 = 12 ⇒ 7 x 7 - 2 = 12
⇒ 49 - 2 = 12 ⇒ 47 = 12
⇒ LHS ≠ RHS
So, option (a) is incorrect.
From option (b), putting the signs in given equation, we get
7 + 7 - 2 x 1 = 12 ⇒ 7 + 7 - 2 = 12
⇒ 14 - 2 = 12 ⇒ 12 = 12
Hence, option (b) is correct and there is no need to check remaining options .

If 73 + 82 = 14, 91 + 21 = 11, then 86 + 24 = ?
Detailed Solution for MCQ: Mathematical Operations- 1 - Question 10

As, 73 + 82 = 14
⇒ (7 - 3) + (8 + 2) = 14
⇒ 4 + 10 = 14
⇒ 14 = 14 and 91 + 21 = 11
⇒ (9 - 1) + (2 + 1) = 11
⇒ 8 + 3 = 11 ⇒ 11 = 11
Similarly, 86 + 24 = (8 - 6) + (2 + 4) = 2 + 6 = 8
