Are the WAEC objective questions difficult? Let’s quickly move to the Solutions of 2020/2021 WAEC Mathematics Questions
The two zeros before 3 are not counted since they are not between whole numbers
0.064^(-1/3) = 5/2
3 . y+1/2 – 2y-1/3 = 4
Multiply through by 6
3y + 3 – 4y + 2 = 24
Collecting like terms
6. U = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
T = (2, 3, 5, 7)
M = (1, 3, 5, 7, 5)
(T’ n M’) = the numbers in the union set U but not in T and M
(T’ n M’) = (4, 6, 8, 10)
7. Log9 base 3 – log 8 base 2 / log 9 base 3
Log3^2 base 3 – log2^3 base 2 / log 3^2
2log3 base 3 – 3log2 base 2 / 2log3 base 3
Log3 base 3 = 1
Log 2 base = 1
Reason : Log to its own base is 1
This implies:
2 -3 /2 = -1/2
8. Convert both sides to base ten
2xy^1 + 3Xy^0 = 1×2^3 + 1×2^2 + 1x 2^1 + 1×2^0
2y +3 = 8 + 4 + 2 + 2 + 1
2y + 3 = 15
Y = 12/2 = 6
9. 6, p, 14
First term a = 6, third term = 14
Number of terms of A.P = a + (n-1)d
T3 =14 = a + 2d
6 + 2d = 14
Common difference d = 14
P = second term
T2 = a + d = 6 + 4 = 10
10. 4 SQRT(7) – 15 SQRT(2) + 6 SQRT(2)
4 SRT(7) – 9 SRT(2)
11 . m/n = 2/1
3(2n)^2 – 2n^2 / 2n^2 +2n^2
12n^2 – 2n^2 / 4n^2 + 2n^2 = 10n^2/6n^2
12. H = kp / y^2 where k = constant, H = 1, p = 8, y = 2
k = Hy^2 /p = 4×1/8 = ½
13. Factorizing:
(4x^2 -6x)(-10x +15)
2x(2x – 3)-5(2x – 3)
2x-5 = 0 or 2x-3 = 0
X = 5/2 or x = 3/2
16. 15 percent profit = 115 = 6,900 naira
Let the percent Bala sold the article at 6600 naira = x
115 = 6,900
Cross multiplying
6900x = 759000
X = 110 percent
The percentage profit if he had sold it at 6600 naira = 110 – 100
= 10 percent
17. 3p = 4q
9p = 8q – 12
8q – 12 -(36q/3)
24q – 36 – 36q
p = -4, pq = -3x-4 = 12
18. (0.25)^y = 32
(1/4)^y = 32
20. (x-7)(x+2)/ (x+7)(x+2) = (x-7) / (x+7)
21. 3p – 1/p^2 -p
It will be undefined when the denominator p^2 – p = 0
therefore, p = 1 would make it zero
T.S.A = 165 cm^2
T.S.A = 2pirh + 2pir^2
165 -2x(22/7)x3.5^2 = 2x(22/7) x3.5h
165 – 77 = 22h,

23. 2^a = SQRT(64)
but b/a = 3
therefore, b = 3a = 3×3 = 9
a^2 + b^2 = 3^2 + 9^2 = 90
24. Angle XYZ = 180 – (90+52)
180-142 = 38 degrees
From sin rule,
XZ/sin38 = 32/sin52
26. tita = 72
arc length = 2pir(tita/360)
arc length = 2x( 22/7 )x3.5x(72/360) = 4.4 cm
27. 2lb = (a+b)h
2lb = ah + bh
2lb- bh = ah
b(2l-h) = ah
b = ah/2l-h
28. agent commission = 8 percent
percentage received by eric = 100 – 8 = 92
let the selling price be x
92x/100 = 117760
x = 11776000/92
x = 128000.00 dollars
29. arc length = 2pir(tita/360)
22 = 2×22/7x15xtita/360
tita = 55440/660
tita = 84 degrees
if its sides are doubled,
area = 30* 2x = 60x cm^2
31. A 32. A 33. B 34. D 35. D 36. C 37. D 38. D 39. C 40. C 41. B 4 2. C 43. C 44. D 45. C 4 6 A 47. A 48. C 49. C 50. A

Are the WAEC objective questions difficult? Let’s quickly move to the Solutions to Last year’s WAEC Mathematics Questions.
The two zeros before 3 are not counted since they are not between whole numbers
0.064^(-1/3) = 5/2
3. y+1/2 – 2y-1/3 = 4
Multiply through by 6
3y + 3 – 4y + 2 = 24
Collecting like terms
6. U = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
T = (2, 3, 5, 7)
M = (1, 3, 5, 7, 5)
(T’ n M’) = the numbers in the union set U but not in T and M
(T’ n M’) = (4, 6, 8, 10)
7. Log9 base 3 – log 8 base 2 / log 9 base 3
Log3^2 base 3 – log2^3 base 2 / log 3^2
2log3 base 3 – 3log2 base 2 / 2log3 base 3
Log3 base 3 = 1
Log 2 base = 1
Reason: Log to its own base is 1
This implies:
2 -3 /2 = -1/2
8. Convert both sides to base ten
2xy^1 + 3Xy^0 = 1×2^3 + 1×2^2 + 1x 2^1 + 1×2^0
2y +3 = 8 + 4 + 2 + 2 + 1
2y + 3 = 15
Y = 12/2 = 6
9. 6, p, 14
First term a = 6, third term = 14
Number of terms of A.P = a + (n-1)d
T3 =14 = a + 2d
6 + 2d = 14
Common difference d = 14
P = second term
T2 = a + d = 6 + 4 = 10
10. 4 SQRT(7) – 15 SQRT(2) + 6 SQRT(2)
4 SRT(7) – 9 SRT(2)
11. m/n = 2/1
3(2n)^2 – 2n^2 / 2n^2 +2n^2
12n^2 – 2n^2 / 4n^2 + 2n^2 = 10n^2/6n^2
12. H = kp / y^2 where k = constant, H = 1, p = 8, y = 2
k = Hy^2 /p = 4×1/8 = ½
13. Factorizing:
(4x^2 -6x)(-10x +15)
2x(2x – 3)-5(2x – 3)
2x-5 = 0 or 2x-3 = 0
X = 5/2 or x = 3/2
16. 15 percent profit = 115 = 6,900 naira
Let the percent Bala sold the article at 6600 naira = x
115 = 6,900
Cross multiplying
6900x = 759000
X = 110 percent
The percentage profit if he had sold it at 6600 naira = 110 – 100
= 10 percent
17. 3p = 4q
9p = 8q – 12
8q – 12 -(36q/3)
24q – 36 – 36q
p = -4, pq = -3x-4 = 12
18. (0.25)^y = 32
(1/4)^y = 32
20. (x-7)(x+2)/ (x+7)(x+2) = (x-7) / (x+7)
21. 3p – 1/p^2 -p
It will be undefined when the denominator p^2 – p = 0
therefore, p = 1 would make it zero
T.S.A = 165 cm^2
T.S.A = 2pirh + 2pir^2
165 -2x(22/7)x3.5^2 = 2x(22/7) x3.5h
165 – 77 = 22h,
Are you enjoying the Solutions to WAEC Mathematics Questions? Let’s continue.
23. 2^a = SQRT(64)
but b/a = 3
therefore, b = 3a = 3×3 = 9
a^2 + b^2 = 3^2 + 9^2 = 90
24. Angle XYZ = 180 – (90+52)
180-142 = 38 degrees
From sin rule,
XZ/sin38 = 32/sin52
26. tita = 72
arc length = 2pir(tita/360)
arc length = 2x( 22/7 )x3.5x(72/360) = 4.4 cm
27. 2lb = (a+b)h
2lb = ah + bh
2lb- bh = ah
b(2l-h) = ah
b = ah/2l-h
28. agent commission = 8 percent
percentage received by eric = 100 – 8 = 92
let the selling price be x
92x/100 = 117760
x = 11776000/92
x = 128000.00 dollars
29. arc length = 2pir(tita/360)
22 = 2×22/7x15xtita/360
tita = 55440/660
tita = 84 degrees
if its sides are doubled,
area = 30* 2x = 60x cm^2
31. A 32. A 33. B 34. D 35. D 36. C 37.D 38. D 39. C 40. C 41. B42. C 43. C 44. D 45. C46 A 47.A 48. C 49. C 50. A
