(a)
Paint needed for 1 table = 1 u
Paint needed for 1 cupboard = 5 u
Paint needed for 5 tables and 2 cupboards
= 5 x 1 u x 2 x 5 u
= 5 u + 10 u
= 15 u
35 of the paint = 15 u
15 of the paint = 15 u ÷ 3 = 5 u
Fraction of the remaining paint left
= 1 -
35=
25 25 of the paint = 2 x 5 u = 10 u
Remaining paint left = 10 u
Number of tables that Adam can paint with the remaining paint
= 10 u ÷ 1 u
= 10
(b)
Number of cupboards that Adam can paint with the remaining paint
= 10 u ÷ 5 u
= 2
Answer(s): (a) 10; (b) 2
