31.	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 ?
	A.	339
	B.	349
	C.	369
	D.	None of Above

Answer: Option B

Explanation:

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	is a whole number is p = 26
	17

x = (13 x 26 + 11)

= (338 + 11)

= 349
