When a number is divided by 13, the remainder is 11. When the same number is divided by 17, then remainder is 9. What is the number ?


Options:
A .  339
B .  349
C .  369
D .  Data inadequate
Answer: Option B

x = 13p + 11 and x = 17q + 9

 When A Number Is Divided By 13, The Remainder Is 11. When T... 13p + 11 = 17q + 9

 When A Number Is Divided By 13, The Remainder Is 11. When T... 17q - 13p = 2

 When A Number Is Divided By 13, The Remainder Is 11. When T... q = 2 + 13p 17

The least value of p for which q = 2 + 13p is a whole number is p = 26 17

 When A Number Is Divided By 13, The Remainder Is 11. When T... x = (13 x 26 + 11)

   = (338 + 11)

   = 349
