completely tired after solving so many questions of data interpretation no improvement, feeling so bad
PLEASE ANSWER!!
In a certain examination paper, taken by a total of 36000 students, there are q questions. For p = 1, 2 .. q, there are 2^(q - p) students who answered p or more questions wrongly. The total number of wrong answers is 65,535.
I understood the solution till..
students with 1 or more wrong answers = 2^(q-1)students with 2 or more wrong answers = 2^(q-2) and so on
Hence, students with exactly 1 wrong answer = 2^(q-1) - 2^(q-2) = 2^(q-2) students with exactly 2 wrong answers = 2^(q-2) - 2^(q-3) = 2^(q-3)..
students with exactly q wrong answers = ??? (in solution its given 2^0)
So, No. of WRONG ANSWERS is summations of (students with exactly p wrong ans)*p = 1*2^(q-2) + 2*2^(q-3)+ 3*2^(q-4).....+ q*2^0 = 2^(q-1)+ 2^(q-2)+ 2^(q-3).....+1 How??
