• 4+2=6 and add 10 ----->6+10=60
  5+3=8 and add 10------>8+10=80
  so answer D
• 8 years agoHelpfull: Yes(8) No(13)
• 4+2 = 6
  6+0 = 6
  5+3 = 8
  4+4 = 8
  
  So, 44 is correct.
  
  60-42 = 18
  71-53 = 18
  
  So, 71 is correct.
  
  4+2=6 and 6*10=60
  5+3=8 and 8*10=80
  
  So, 80 is correct.
  
  All are correct

• 42:60::53:x
  42*x=60*53
  x=75.7
  x=80
• 8 years agoHelpfull: Yes(4) No(1)
• answer is E
  because the adding value is 53+18=71
  4+2=6 then add 0=60
  similarly 5+3=8 then add 0=80
• 8 years agoHelpfull: Yes(3) No(4)
• 42:60 -> 42+18=60
  i.e 53+18=71
  answer is B

• 3 yrs ago sum = A+j+m=52
  
  present ages sum= A+j+m=61
  
  J=M-1 or M =J+1
  
  J-4 =3/2(A-4)
  
  A= (2 J+4)/3
  
  Substitute all in Second eqn of Sum of present ages
  
  (2j+4)/3 + j + j +1 =61
  
  8j =176
  j=22 present , m= 23 present
  
  after 2 yrs sum = (22+2) +(23+2) =49

• c) 71
  
  In 2 Ways
  
  1. 4+1 = 5, 2+1= 3 ----------> 53
  6+1 = 7,0+1 = 1 ----------> 71
  
  2. 42+18 = 60 So, 53+18 = 71

• 42+18=60 => 53+18=71 ==>( Ans is B and C )
  ( OR )
  4+2=6=>6+10=60 => 5+3=8=>8+10=80 ==>( Ans is D )

• 42:60::53:?
  60-42=18=42+18
  therefore
  53+18=71
  ans is c =71
• 7 years agoHelpfull: Yes(0) No(0)
• Ans B.71
  42-53=11
  60-71=11
• 7 years agoHelpfull: Yes(0) No(1)
• 71. Because 53+18=71 and 42+18=60
