## WAEC 2021 GCE Mathematics Theory past questions for practice

The objectives part of the exams is always very simple. you will be expected to take just an option from multiple choices./ make sure you go through the question over and over again before making your choice.

Below are sure WAEC GCE Mathematics questions for your practice.

**Question 1——WAEC GCE Mathematics **

1a) Using sine rule

b/sin20 = 6/sin30

bsin30 = 6sin120

b 6sin120/sin30

b = 6×0.2511/0.4540

b = 5.7063/0.4540

b = 12.57 ≠ 12.6cm

1b i) I = PRT/100, p=N15000 R=10% and I=3years

A = P+ I

where I = 15000*10*3/100=N4500

A=4500+15000 =N19500

ii) I = PRT/100, p=N15000 R=10% and I=3years

A = P+ I

where I = 15000*10*3/100=N4500

A=4500+15000 =N19500

**Question 2——WAEC GCE Mathematics Answers and questions **

2a)

T=thickness

P=Pages

T*P

T=KP

T=3

P=900

3=900k

k=3/900=1/300

T=P/300

WHERE T=45CM

P=?

45=P/300

P=300*45

P=13500pages

2b)

x + y =3______(1)

x² – y² = 15_____(2)

Solution

From equation (2)

x² – y² = 15

(x+y)(x-y) = 15_____(3)

Recall x-y = 3

Substitute the value of (x-y) in equation (3)

3(x + y) = 15

Therefore (x +y) =5

The value of x+y =5

The mathematics questions above is simple as you can see in the solving provided, so study it and you may likely see same in the Exam hall.
