## NECO GCE Mathematics past questions for practice

Below are sure NECO GCE Mathematics questions for your practice.

### NECO GCE mathematics Essay Questions

**Question 1——NECO 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——NECO 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 NECO GCE 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.

**Question 3—–NECO mathematics Answers and questions **

P=N300,000

R=7^1/2%

T=3yrs

At the end of year 1

I=PRI/100=300000*15*1/100*2

I=N22500

2nd Year

P=300000+22500+50000

=N372500

I=372500*15*1/200=N27937.50

3rd Year

P=372500+27937.5+50000

=N450437.50

I=450437.50*15*1/200

I=N33782.81

total saving of 3years

=450437.5+33782.81+50000

=N534220.31

**Question 4——–NECO 2018 GCE Mathematics answers **

n(y)=40

n(c)=35

n(b)=26

n(CnB)=x

drawing

40=35-x+x+26-x

40=61-x

x=61-40=21

21 student offer both

3b)

U:{all positive <-20 br=””>S:{all even number <14 br=””>T:{all even nus<-20divisible 3=”” br=”” by=””>U={1,2,3,,,20}

S={2,4,6,8,10,12}

T={6,12,18}

SUT={2,4,6,8,10,12,18}

As a matter of fact, NECO mathematics syllabus is the best guide you should work with.The syllabus will guide you properly and keep you on the right track.

**Question 4———-NECO GCE Mathematics Answers and questions**

length of chord

=2rsm^θ/2

=2*4sm^9^4/2

=85m47

=8*0.7314

=5.85cm

4b)

draw the diagram

7cm>7cm

area(A)=θper^2/360-1/2r^2 8mθ

=r^2/2{22/180-8mθ}

=49/2[90/180*22/7-8m90]

=49/2{1/2*22/77-1}

=49/2{11/7-1}=44/2{1.57-1}

=49/2{0.57}=13.97cm^2

Like the NECO math question above, it is under Geometry. If you check the NECO GCE mathematics syllabus very well, you will see this topic.

A situation where you sit in the exam hall and don’t know what to write will be solved if and only if you study these questions.
