Instruction : Answer all the questions in Section A and B. Shade your answers for section A in the objective answer sheet. Answer section B in the space provided.

1 Round off 241 356 to 3 significant figures.A 240 000 C 241 300B 241 000 D 241 400

2 Factorise t2 – 4t – 21.A ( t – 4 ) ( t + 3 ) C ( t + 4 ) ( t – 7 )B ( t + 3 ) ( t – 7 ) D ( t – 21 ) ( t + 1 )

3 Givenξ = { x : 12 ≤ x ≤ 36 , x is an integer }E = { x : x is a number such that the sum of its digits is 8 } andF = { x : x is a multiple of 2 }

Find n ( E
