Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the given equation.
20 * 96 * 66 * 11 * 10 * 56
– , ×, ÷ , + , =
– , + , ÷ ,×, =
Correct answer
Why this answer is correct
Given: 20 * 96 * 66 * 11 * 10 * 56480÷0.3×5+500190+9×27÷1.6=2480÷0.3×5+500190+9×27÷1.6=2480÷0.3×5+500190+9×27÷1.6=2
According to the question, after replacing the signs:
Option 1): + , – , ÷ , ×, =
20 * 96 * 66 * 11 * 10 * 56 ⇒ 20 + 96 - 66 ÷ 11 × 10 = 56
⇒ 20 + 96 - 66 ÷ 11 × 10 = 56
⇒ 20 + 96 - 6 × 10 = 56
⇒ 20 + 96 - 60 = 56
⇒ 116 - 60 = 56
⇒ 56 = 56 (LHS = RHS)
Option 2): + , – , ÷ , = , ×
20 * 96 * 66 * 11 * 10 * 56 ⇒ 20 + 96 - 66 ÷ 11 = 10 × 56
⇒ 20 + 96 - 66 ÷ 11 = 10 × 56
⇒ 20 + 96 - 6 = 560
⇒ 116 - 6 = 560
⇒ 110 ≠ 560 (LHS ≠ RHS)
Option 3): – , ×, ÷ , + , =
20 * 96 * 66 * 11 * 10 * 56 ⇒ 20 - 96 × 66 ÷ 11 + 10 = 56
⇒ 20 - 96 × 66 ÷ 11 + 10 = 56
⇒ 20 - 96 × 6 + 10 = 56
⇒ 20 + 10 - 576 = 56
⇒ 30 - 576 = 56
⇒ -546 ≠ 56 (LHS ≠ RHS)
Option 4): – , + , ÷ ,×, =
20 * 96 * 66 * 11 * 10 * 56 ⇒ 20 - 96 + 66 ÷ 11 × 10 = 56
⇒ 20 - 96 + 66 ÷ 11 × 10 = 56
⇒ 20 - 96 + 6 × 10 = 56
⇒ 20 + 60 - 96 = 56
⇒ 80 - 96 = 56
⇒ -16 ≠ 56 (LHS ≠ RHS)
Hence, "Option 1" is the correct answer.

The rest of the elements shift clockwise.
2) Second box series →
The 2nd row elements shift anticlockwise.
The rest of the elements shift anticlockwise.
Thus, the final series is:
Hence, "Option 3" is the correct answer.
Select the set in which the numbers are related in the same way as are the numbers of the given sets.
(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 – Operations on 13 such as adding/ deleting/ multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.

(349, 145, 206)
(191, 891, 118)
(245, 213, 122)
Correct answer
(389, 183, 206)
Why this answer is correct
The logic followed here is:
Logic: 2nd number + 3rd number = 1st number.
Now,
For (428, 150, 278):
⇒ 150 + 278
= 428.
For (401, 139, 262)
⇒ 139 + 262
= 401.
Similarly, for Option 1: (389, 183, 206)
⇒ 183 + 206
= 389.
Hence, the correct answer is Option 1.

5
Correct answer
1
Why this answer is correct
The logic followed here is :-
From the given three different dices the adjacent sides are as shown below :
As 3 is common on both the dices figure 1 and figure 2, it is clear that 6, 2, 5, and 4 are adjacent to it, and the remaining i.e. 1 will be opposite to it.
Opposite pairs:
6 → 5
2 → 4
3 → 1
So, the opposite side of "3" will be side "1".
Hence, the correct answer is "Option 3".

Correct answer
4
Why this answer is correct
The logic followed here is :-
From the given two different dices the adjacent sides are as shown below :
As 4 is common on both the dices, it is clear that 5, 6, 3, and 1 are adjacent to it, and the remaining i.e. 2 will be opposite to it.
Opposite pairs:
6 → 3
5 → 1
4 → 2
So, the opposite side of "2" will be side "4".
Hence, the correct answer is "Option 2".

168
158
185
186
Correct answer
186
Why this answer is correct
The logic followed here is:
Logic: (1st number)2 + 17 = 2nd number.
Now,
For, 98 ∶ 9
⇒ 92+ 17 = 81 + 17 = 98.
For, 458 ∶ 21

.
Option 2)
⇒ Can be made because all are the opposite sides.
Option 3)
⇒ Cannot be made because

− and +
÷ and ×
− and ×
Correct answer
Why this answer is correct
Given: 7 – 4 × 40 ÷ 5 + 6 = 51480÷0.3×5+500190+9×27÷1.6=2480÷0.3×5+500190+9×27÷1.6=2480÷0.3×5+500190+9×27÷1.6=2
According to the question, after interchanging the signs:
Option 1): − and +
7 – 4 × 40 ÷ 5 + 6 = 51 ⇒ 7 + 4 × 40 ÷ 5 – 6 = 51
⇒ 7 + 4 × 40 ÷ 5 – 6 = 51
⇒ 7 + 4 × 8 – 6 = 51
⇒ 7 + 32 – 6 = 51
⇒ 39 – 6 = 51
⇒ 33 ≠ 51 (LHS ≠ RHS)
Option 2): ÷ and ×
7 – 4 × 40 ÷ 5 + 6 = 51 ⇒ 7 – 4 ÷ 40 × 5 + 6 = 51
⇒ 7 – 4 ÷ 40 × 5 + 6 = 51
⇒ 7 – 0.1 × 5 + 6 = 51
⇒ 7 + 6 – 0.5 = 51
⇒ 13 – 0.5 = 51
⇒ 12.5 ≠ 51 (LHS ≠ RHS)
Option 3): − and ×
7 – 4 × 40 ÷ 5 + 6 = 51 ⇒ 7 × 4 - 40 ÷ 5 + 6 = 51
⇒ 7 × 4 - 40 ÷ 5 + 6 = 51
⇒ 7 × 4 - 8 + 6 = 51
⇒ 28 + 6 - 8 = 51
⇒ 34 - 8 = 51
⇒ 26 ≠ 51 (LHS ≠ RHS)
Option 4): + and ×
7 – 4 × 40 ÷ 5 + 6 = 51 ⇒ 7 – 4 + 40 ÷ 5 × 6 = 51
⇒ 7 – 4 + 40 ÷ 5 × 6 = 51
⇒ 7 – 4 + 8 × 6 = 51
⇒ 7 + 48 – 4 = 51
⇒ 55 – 4 = 51
⇒ 51 = 51 (LHS = RHS)
Hence, "Option 4" is the correct answer.
