kunti had 4 sons. each sibling is either 1 year older or younger.she multiply their ages and write in a diary. all born on 1st april year different. ques was lyk dis..
multiplication f agees will be..
option..
1. prime number +1.
2.a square number -1.
3. divisible by 10 always.
4.divisible by previous number.

• @swati. 119 is not a prime number...answer will be square number -1.
  consider..
  1*2*3*4=24....=25-1
  2*3*4*5=120...=121-1
  3*4*5*6=360..=361-1
  4*5*6*7=840...=841-1
  5*6*7*8=1680..=1681-1
  6*7*8*9=3024..=3025-1

• first take 1 2 3 4
  product=24
  option1--> 23+1 satisfies
  option2--> 5^2-1 satisfies
  so take 2 3 4 5
  product=120
  0pt 1--> 119+1=120
  but 119=17*7 so not a prime number
  opt 2--> 11^2-1=121-1=120 satisfies.
  so answer is option 2......(square of a number-1)

• take age as 1,2,3,4
  1*2*3*4=24(prime number(23)+1 , sqr(5)-1) satisfies
  
  now take 2,3,4,5
  2*3*4*5=120(sqr(11)-1)
  
  Hence answer is [a square number - 1]

• The diff. of age is +1 or -1 from each other so, we can take the ages of all four in a series like 1,2,3,4 or 2,3,4,5 as it is
  Now let take their ages as 1,2,3,4
  
  product of ages will be - 1*2*3*4 = 24
  check condition 23+1 satisfies
  25-1 satisfies
  24/10 not= 0 not satisfies
  24/23 not= 0 not satisfies
  Now take the ages as 2,3,4,5
  PRODUCT 2*3*4*5 = 120
  Check Conditions 119+1 not satisfies
  121-1 satisfies
  
  ans. = square - 1

• suppose that ages are x,x+1,x+2,X=3
  x*(x+1)*(x+2)*(x+3)=x^4 + 6x^3 + 11x^2 + 6x
  
  now we can put 1,2,3.... any thing we will get a square-1

• 1. prime number +1.
• 9 years agoHelpfull: Yes(0) No(18)
• 1. Prime number +1

• according to the auestion each sibling is 1 year older or younger so considering that their age is 2,3,4,5 we will get the product 120
  hence 119+1
  so the ans is +1

• let youngest is of 1 year old then second will be of 2 year third will be of 3 year and oldest is of 4 year.multiply of these will be 24.so we have two option 1 and 2.if we have yongest as two year old option 2 is wrong.se option 1 is right answer.

• ans is option 2
  given qustn is each sibling one year old or young so ages will be 1,2,3,4 or 5,4,3,2 etc ... calculate ages multiplication 1*2*3*4=24 means 5^2-1 or 5*4*3*2=120 means 11^2-1..... i hope u may clear
