Q. How many 1's present in the binary form of number 519*1024+11*64+3

• Easiest way to do this type of questions:
  519*1024+11*64+3 = (2^9+2^2+2^1+2^0)*(2^10)+(2^3+2^1+2^0)*(2^5)+(2^1+2^0) = 2^19+2^12+2^11+2^10+2^8+2^6+2^5+2^1+2^0
  number of 2^something = number of 1's = 9 (answer)

• 9 1's are present
• 10 years agoHelpfull: Yes(7) No(4)
• ans=9 1's
  519*1024+11*64+3
  lets start with multiplication,
  519*1024 =1000000111*10000000000 (binary multiplication)= 10000001110000000000
  1.e 1000000111 followed by 10 zeros
  
  11*64=1011 * 1000000 = 1011000000 (total 10 digit)
  at last
  3=11
  (it is clear here no need of further addition)
  total 1's = 4+3+2 =9

• 1000000111+10000000000+1011+1000000+11= eleven(11) ones(1) are present... so option is 11
  (Hint: divide the numbers with 2)

• 10 1's are there
• 10 years agoHelpfull: Yes(3) No(2)
• 9 times "1"
• 10 years agoHelpfull: Yes(2) No(1)
• options were 1)9 2)10 3)12 4)none of these.
  there was no 11 there.
  and we have to find the number of 1's in the number we get by adding all these.

• there are 9 ones

• 11 one's present.1st see in 512 ,one 1 is their,and(512+7)in 7 three 1 are their.so in 519 ,4 ones are their and in 1024 one 1 is present.and operation of 519 and 1024 gives 5 ones...like this u hav to do..
• 10 years agoHelpfull: Yes(1) No(4)
• 519*1024+11*64+3 = 532136 ( by solving )
  then convert into binary by dividing 2... u will get binary number which consists 9 '1'.... so ans is 9.... sure..... just do it....

• 519*1024+11*64+3 can be written as=
  (2^9+2^2+2^1+2^0)2^10+(2^3+2^1+2^0)2^6+2^1+2^0
  =2^19+2^12+2^11+2^10+2^9+2^7+2^6+2^2+2^0
  
  = 9 times 1
  hence there are 9 1's

• 11 1's present
• 8 years agoHelpfull: Yes(0) No(0)
• 519*1024+11*64+3=605891
  605891 binary is 10010011111011000011
  ie 11 1's present
