879 ? (7 + 9) - 8 = 8
625 ? (2 + 5) - 6 = 1
and 586 ? (8 + 6) - 5 = 9
Similarly, 785 ? (8 + 5) - 7 = 6
Here sign '&' does not convey any meaning and sign '%' signifies '+'
26 + 7 = 33, 46 + 8 = 54
Therefore, 6 + 89 = 95
(2)3 ÷ 4 = 2, (4)4 ÷ 8 = 32
Therefore, (6)2 ÷ 4 = 9
Given equation ? 15 * 24 * 3 * 6 * 17
From option (a), substitute the signs
15 + 24 ÷ 3 - 6 = 17
? 15 + 24/3 - 6 = 17
? 15 + 8 - 6 = 17
? 23 - 6 = 17
? 17 = 17
Apply all option one by one.
? 6 x 4 + 2 = 16 ? 4 + 6 x 2 = 16 ? 4 + 12 = 16
H ? T ...(i) T ? M ...(ii) M > F ...(iii)
From (i) and (ii) H and M can't be compared. Hence II does not follow
From (ii) and (iii) F and T can't be compared. Hence I does not follow
As, 122 + 5 2 ? 144 + 25 = 169
42 + 22 ? 16 + 4 = 20
and 12 + 52 ? 1 + 25 = 26
Similarly,
72 + 32 = 49 + 9 = 58
Solve the equation by using option one by one.
5 * 6 * 5 * 8 * 14
From option (b),
After changing the symbol as per question,
5 x 6 ÷ 5 + 8 = 14
Apply the BODMAS Rule,
? 5 x 6/5 + 8 = 14
? 14 = 14
Given question is,
40 x 12 + 3 - 6 ÷ 60
According to the question, putting the real values of signs,
40 + 12 ÷ 3 x 6 - 60 = 40 + 4 x 6 - 60
Apply the BODMAS Rule
= 40 + 24 - 60 = 64 - 60 = 4
Solve all option one by one,
36 + 6 - 3 x 2 = 20
After changing the symbol as per question,
36 ÷ 6 x 3 + 2 = 20
Apply the BODMAS rule,
? 6 x 3 + 2 = 20
? 18 + 2 = 20
? 20 = 20
Conclusions
As per given question, we can draw the below conclusion,
I. D > N (?)
II. C ? K (X)
