SECTION A: OBJECTIVE TEST

1.(a) $1$ bird costs $$240$

Actual cost of $360$ birds $= 360 × $240$

$= $86400$

(1 mark)

1.(b) Estimated cost of $360$ birds $= 400 × $200$

$= $80000$

(1 mark)

TOTAL = 2 MARKS

2.(a) $50$ bags of cement $= 2.5$ tonnes

$1$ bag of cement $= 2.5$ divided by $50$

(1 mark)

$= 0.05$ ton

(1 mark)

But $1$ tonne is $1000kg$

(1 mark)

Therefore $0.05 = 0.05 × 1000$

$= 50kg$

(2 marks)

2.(b) $1000cm^3 = 1 L$

$76530 cm^3 = \frac{76530}{1000}$
