= 60
Answer: Option A. -> - and +
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.
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.
Answer: Option B. -> + - x
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.
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.
Answer: Option D. -> x ÷ =
Answer: (d)
Since, 16 x 6 ÷ 4 = 24
⇒ $96/4$ = 24
⇒ 24 = 24
Answer: (d)
Since, 16 x 6 ÷ 4 = 24
⇒ $96/4$ = 24
⇒ 24 = 24
Answer: Option A. -> ÷ x - =
Answer: (a)
Since, 9 ÷ 3 x 3 - 3 = 6
⇒ 3 x 3 - 3 = 6
⇒ 9 - 3 = 6
⇒ 6 = 6
Answer: (a)
Since, 9 ÷ 3 x 3 - 3 = 6
⇒ 3 x 3 - 3 = 6
⇒ 9 - 3 = 6
⇒ 6 = 6
Answer: Option B. -> = x +
Answer: (b)
From option (b).
24 = 4 x 5 + 4
⇒ 24 = 20 + 4
⇒ 24 = 24
Answer: (b)
From option (b).
24 = 4 x 5 + 4
⇒ 24 = 20 + 4
⇒ 24 = 24
Answer: Option B. -> O
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.
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.
Answer: Option B. -> x - ÷
Answer: (b)
Since, 8 * 6 * 96 * 2 = 0
⇒ 8 x 6 - 96 ÷ 2 = 0
⇒ 48 - 48 = 0
Answer: (b)
Since, 8 * 6 * 96 * 2 = 0
⇒ 8 x 6 - 96 ÷ 2 = 0
⇒ 48 - 48 = 0
Answer: Option C. -> 15
Answer: (c)
According to the question,
? = 7 - 10 × 5 ÷ 6 + 4
from the question by changing the symbols, we get
= 7 + 10 ÷ 5 × 6 - 4 (using VBODMAS rule)
=7 + 2 × 6 - 4
= (7 + 12) - 4
= 15
Answer: (c)
According to the question,
? = 7 - 10 × 5 ÷ 6 + 4
from the question by changing the symbols, we get
= 7 + 10 ÷ 5 × 6 - 4 (using VBODMAS rule)
=7 + 2 × 6 - 4
= (7 + 12) - 4
= 15
Answer: Option A. -> 9
Answer: (a)
According to the question,
? = 4 D 16 A 5 B 8 C 5
from the question by changing the symbols, we get
= 4 + 16 × 5 ÷ 8 - 5 (using VBODMAS rule)
= 4 + 16 × 0.625 - 5
= 4 + 10 - 5
= 14 - 5 = 9
Answer: (a)
According to the question,
? = 4 D 16 A 5 B 8 C 5
from the question by changing the symbols, we get
= 4 + 16 × 5 ÷ 8 - 5 (using VBODMAS rule)
= 4 + 16 × 0.625 - 5
= 4 + 10 - 5
= 14 - 5 = 9
