• ans)D(any two of three)
  from I) A-5 = 2(S-5)
  from II)6A = 11S
  from III)7A = 12S+25
  from three equ we can solve ages by any of two......
• 11 years agoHelpfull: Yes(13) No(2)
• as the option3 doesnt specify the ages so tha answer is only 1 and 2
• 12 years agoHelpfull: Yes(2) No(6)
• any two of three
• 10 years agoHelpfull: Yes(1) No(0)
• I guess it E none of these
  coz taking option A we get x=25
  Taking option C we get x=25
  but when we take 2 and 3 we dont get the answer x=19
