When Ganesh was asked about his score in the last
classroom test in which the maximum marks were
50, he replied, "The ratio of 15 less than my score to
15 more than three times my score is 1:5". What is
his score?
(A) 35
(B) 40
(C) 45 (D) 50

CelluloseTaking LHS:
sin 105° + cos 105°
cos (90° - 105°) + cos 105°
cos 15° + cos 105°
cos C + cos D = 2(cos(C+D)/2)(cos(C-D)/2)
2cos(120°/2)cos(90°/2)
2cos60°cos45°
2(1/2)cos45°
cos45°
= RHS
Find the Hamming code for binary code 10011. Consider even parity bits.
sin105+cos105=1/√2 prove this question
Calculating the Hamming Code
Mark all bit positions that are powers of two as parity bits. (positions 1, 2, 4, 8, 16, 32, 64, etc.)
All other bit positions are for the data to be encoded. ...
Each parity bit calculates the parity for some of the bits in the code word. ...
Set a parity bit to 1 if the total number of ones in the positions it checks is odd.
Answer:
Lets, Ganesh's score be X.
so, (X -15)/(3X +15) = 1/5
5X - 75 = 3X + 15
2X = 90
X = 45
