the reciprocal of the hcf and lcm of two are 1/12 and 1/312 .if one of the number is 24 then other no. is
a.126 b.136 c.146 d.156

• d. 156
  reciprocal of the hcf and lcm of two are 1/12 and 1/312
  
  so, HCF = 12 , LCM = 312
  
  LCM * HCF = product of two numbers = a*b => b = LCM * HCF / a
  
  so, other = 12*312 / 24 = 156

• A/Q reciprocal of 1/12:-12 & Reciprocal of 1/312:- 312
  
  Than Find another number is ; 12*312/24 = 156
  
  So then the other number is 156

• product of hcf and lcm=product of 2 numbers
  12*312=2*x
  x=(12*312)/2
  x=156

• 2^4=16
  if 16/5 remainder is 1
  similarly
  2^8
  2^12
  .
  .
  .
  2^32 is divided by 5 remainder is 1
  balance is 2^3=8
  if 8/5 remainder is 3
  
  therefore, answer is 3

  let a and b are two no.
  hcf (a,b)=12
  lcm(a,b)=312
  a*b=12*312
  a=24;
  b=12*312/24
  b=156
