1 (a) The number N has the base -10 form N = abba abba … abba, consisting of blocks of four
digits, as shown, where a and b are integers such that 1 G a 1 10 and 0 G b 1 10.
Use a standard divisibility test to show that N is always divisible by 11. [3]
(b) The number M has the base-n form M = cddc cddc … cddc, where n 2 11 and c and d are
integers such that 1 G c 1 n and 0 G d 1 n.
Show that M is always divisible by a number of the form k1 n + k2 , where k1 and k2 are
integers to be determined. [3]
2 A surface S has equation z = 4x y - y x + y2 for x, y H 0.
Determine the equation of the tangent plane to S at the point (1, 4, 20). Give your answer in the
form ax + by + cz = d where a, b, c and d are integers. [5]
3 Determine all integers x for which x / 1 (mod 7) and x / 22 (mod 37) and x / 7 (mod 67).
Give your answer in the form x = qn + r for integers n, q, r with q 2 0 and 0 G r 1 q. [6]

(a) Given that b is not a multiple of a and that a # b = 0, determine all possible sets of values of
p, q and r. [3]
(b) You are given instead that b = ma , where m is an integer with m 2 1.
By writing each of p, q and r in terms of m, show that there is a unique value of m for which
p, q and r are all integers, stating this set of values of p, q and r. [7]
