Question : 1
Which sequence of mathematical symbols can replace * in the given equation to balance the equation?
7 * 7 * 2 * 1= 12
a) x - ÷
b) + - x
c) x - +
d) + x -
Answer »Answer: (b)
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.
Question : 2
Given, B = 8, L = 7, O = 5, C =9 and K =4. Using the given total, find out the missing symbol in the block.
L ? K K K = 24
a) L
b) O
c) B
d) K
Answer »Answer: (b)
L ? K K K = 24
According to the question,
7 + ? + 4 + 4 + 4 = 24
⇒ ? = 24 - 19= 5=0
Hence, O is the missing symbol in the given.
Question : 3
In the following question, * stands for any of the mathematical signs at different places, which are given as choices under each question. Select the choice with the correct sequence of signs which when substituted makes the question as a correct equation.
24 * 4 * 5 * 4
a) x + =
b) = x +
c) + x =
d) = + x
Answer »Answer: (b)
From option (b).
24 = 4 x 5 + 4
⇒ 24 = 20 + 4
⇒ 24 = 24

What should be the correct signs to balance the following equation?
Question : 4
65 40 11=36
a) - and +
b) x and ÷
c) ÷ and +
d) + and x
Answer »Answer: (a)
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.
Question : 5
7 4 8 2 = 24
a) -, x and x
b) -, x and ÷
c) x, - and ÷
d) -, ÷ and x
Answer »Answer: (c)
Let us check all the options one-by-one.
From option (a),
7- 4 x 8 x 2 = 24 (using VBODMAS rule)
⇒ 7 - 64 = 24
⇒ - 57 = 24
∴ LHS ≠ RHS
So, option (a) is incorrect.
From option (b),
7-4 x 8 ÷2 = 24 (using VBODMAS rule)
⇒ 7- 4 x 4 = 24 ⇒ 7 - 16 =24
⇒ -9 = 24
⇒ LHS ≠ RHS
So, option (b) is incorrect.
From option (c),
7 x 4 - 8 ÷ 2=24 (using VBODMAS rule)
⇒ 7 x 4- 4 = 24
⇒ 28 - 4 = 24
⇒ 24 = 24
⇒ LHS =RHS
So, option (c) is correct and hence, there is no need to check option (d).
Question : 6
6 5 4 = 34
a) - and +
b) x and +
c) ÷ and x
d) x and +
Answer »Answer: (b)
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.
