1)Last year pandit was thrice his sister's age. Next year he is only twice
her age. After 5 years what is pandit's age.

a)2 b)12 c)11 d)14

• last year:- x-1=3(y-1)
  next year:- x+1=2(y+1)
  solving we get,x=7
  so,after 5 years x=12.

• Last Year Means "-1" so
  Last year pandit was thrice his sister's age=>(x-1)=3(y-1)......(1)
  
  Then Next Year Means "+1" so
  Next year he is only twice her age=>(x+1)=2(y+1)................(2)
  
  After Solving We Get
  x=3y-2...........................................................(1)
  x=2y+1...........................................................(2)
  
  Next..............
  Put 3y-2=2y+1
  We Get y=3
  
  Substitute y=3 in x=3y-2 and get the value of x we x=3(3)-2=>7
  
  Nw After 5 years what is pandit's age. so itz x+5=>7+5=12.

• 12 ANSWER B IS RIGHT
• 12 years agoHelpfull: Yes(2) No(0)
• let pandits present age is x and his sister age is y..
  last year means (x-1)=3(y-1)
  next year means (x+1)=2(y+1)
  solvingg equation we get x=7 and y=3
  after 5 years pandits age will be (7+5)=12

• (b)Go by option
  Present age of pandit=12-5=7
  One yr ago: Pandit-6 Sister-2(THRIcE)
  One yr hence- Pandit- 8 Sister-4(TWICE)Therefore option B is correct.

• OPTION B:SAME LOGIC
• 12 years agoHelpfull: Yes(0) No(0)
• let us assume the present age of pandit is P and his sister's age is S
  then according to given last year pandit was thrice his sister's age
  --> (P-1) = 3(S-1)
  next year he is twice her age
  -->(P+1)= 2(s+1)
  On solving both the equations,we get
  P = 7 and S= 3
  so after 5 years from now that is P+5 = 7+5 =12 years
  Ans : 12 years
  OPTION : b

• let x= pandit age and y=sister age. x+1=2(y+1) and x-1=3(y-1) so by solving we will get x=7 and y =3 so answer is 12 (as x+7=12)
• 7 years agoHelpfull: Yes(0) No(0)
• 12 as 5 years before that is in present year pandit was 7 years old and 1 year back he was 6 years old that is thrice of her sister's age(2) and next year he will 8 years old that is twice of her sister (4 ).
