If N2 = (7601)8 where N is a positive integer, then the value of N is
|
(241)5
|
|
|
(143)6
|
|
|
(165)7
|
|
|
(39)16

Question 13 Explanation:
N2 = (7601)8
N2 = 7*8*8*8 + 6*8*8 + 0 + 1*8
N2 = 3969
N = (63)10
Now, (241)5 = 2*5*5 + 4*5 + 1 = 71
Option (A) is incorrect.
(143)6 = 1*6*6 + 4*6 + 3 = 63
Option (B) is correct.
N2 = 7*8*8*8 + 6*8*8 + 0 + 1*8
N2 = 3969
N = (63)10
Now, (241)5 = 2*5*5 + 4*5 + 1 = 71
Option (A) is incorrect.
(143)6 = 1*6*6 + 4*6 + 3 = 63
Option (B) is correct.
