Question No 23

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 ?

Select the correct answer


Solution!
x = 13p + 11 and x = 17q + 9
 13p + 11 = 17q + 9
 17q - 13p = 2
 q =(2 + 13p) /17
The least value of p for which q =(2 + 13p) /17is a whole number is p = 26
x = (13 x 26 + 11)
= (338 + 11)
   = 349
