+, ÷, −, ×, =
÷, +, −, ×, =
+, +, −, ×, =
−, ÷, +, +, =
Correct answer
−, ÷, +, +, =
Why this answer is correct
Given equation: 88 * 44 * 22 * 66 * 99 * 251
Let's check each option:
1.Option 1: +, ÷, –, ×, =
After replacing the symbols and Using BODMAS rule,:
88 + 44 ÷ 22 – 66 × 99 = 251
= 88 + 2 – 66 × 99
= 88 + 2 – 6534
= 90 – 6534
= – 6444 ≠ 251.
2.Option 2: ÷, +, −, ×, =
After replacing the symbols and Using BODMAS rule,:
88 ÷ 44 + 22 – 66 × 99 = 251
= 2 + 22 – 66 × 99
= 2 + 22 – 6534
= 24 – 6534
= – 6510 ≠ 251.
3.Option 3: +, +, −, ×, =
After replacing the symbols and Using BODMAS rule,:
88 + 44 + 22 – 66 × 99 = 251
= 88 + 44 + 22 – 6534
= 154 – 6534
= – 6380 ≠ 251.
4.Option 4: −, ÷, +, +, =
After replacing the symbols and Using BODMAS rule,:
88 – 44 ÷ 22 + 66 + 99 = 251

= 253 – 2
= 251 = 251.
Hence, the correct answer is "Option 4".
'A & B’ means ‘A is the sister of B’.
‘A – B’ means ‘A is the mother of B’.
‘A × B’ means ‘A is the husband of B’.
‘A @ B’ means ‘A is the son of B’.
Which of the following options means, ‘L is the father of O’?
L & M × N @ O
L × M – N & O
L × M – N × O
L @ M – N & O
Correct answer
L × M – N & O
Why this answer is correct
Family chart:
Given:‘A & B’ means ‘A is the sister of B’.
‘A – B’ means ‘A is the mother of B’.
‘A × B’ means ‘A is the husband of B’.
‘A @ B’ means ‘A is the son of B’.
Let us first decode the given symbols and then draw a family tree
| A is | ||||
|---|---|---|---|---|
| Symbol | @ | & | - | × |
| Meaning | Son | Sister | Mother | Husband |
| of B |
Now, checking the options to find, ‘L is the father of O’.
Option 1: L & M × N @ O
L & M means L is the sister of M.
M × N means M the husband of N.
N @ O means N is the son of O.
So option (1) is not true. Because N cannot be male and female at the same time.
Option 2: L × M – N & O
Here L × M means L is the husband of M.
M - N means M is the mother of N. So it can be said that L is the father of N.
Now N & O means N is the sister of O . So the father of O is also L.
Here, ‘L is the father of O’.
Optionc 3: says L × M – N × O
L × M says that L is the husband of M.
M - N says M is the mother of N.
N × O-says N is the husband of O.
So, L is father in law of O.
Option 4: L @ M – N & O
L @ M says that L is the son of M.
M-N says that M is the mother of N.
N & O says that N is the sister of O.
So, L is brother of O.
So option (2) L × M – N & O represents ‘L is the father of O’.
Hence, the correct answer is: Option (2).

Which of the following interchange of signs would make the given equation correct?
42 ÷ 7 − 64 + 11 × 6 = 4
÷ and −
× and +
× and −
Correct answer
Why this answer is correct
The given equation is
42 ÷ 7 − 64 + 11 × 6 = 4
Now, interchanging the symbols then equation will be:
Option 1: ÷ and −
42 - 7 ÷ 64 + 11 × 6
= 42 - 0.1 + 11 × 6
= 42 - 0.1 + 66
= 108 - 0.1
= 107.9 ≠ 4
Option 2: × and +
42 ÷ 7 − 64 × 11 + 6
= 6 - 64 × 11 + 6
= 6 - 704 + 6
= 12 - 704
= -692 ≠ 4
Option 3: × and −
42 ÷ 7 × 64 + 11 - 6
= 6 × 64 + 11 - 6
= 384 + 11 - 6
= 395 - 6
= 389 ≠ 4
Option 4: + and -
42 ÷ 7 + 64 - 11 × 6
= 6 + 64 - 11 × 6
= 6 + 64 - 66
= 70 - 66
= 4 = 4.
Hence the equation will be corrected after interchanging "+ and −".
Hence, the correct answer is "Option 4".
