MATHEMATICS (Jamb Questions and Answers)


  1. A group of market women sell at least one of yam, plantain and maize. 12 of them sell maize, 10 sell yam and 14 sell plantain. 5 sell plantain and maize, 4 sell yam and maize, 2 sell yam and plantain only while 3 sell all the three items. How many women are in the group?



A. 25

B. 19

C. 18

D. 17

Correct Answer: Option A

Explanation

Let the three items be M, Y and P.

n{M ∩ Y} only = 4-3 = 1

n{M ∩ P) only = 5-3 = 2

n{ Y ∩ P} only = 2

n{M} only = 12-(1+3+2) = 6

n{Y} only = 10-(1+2+3) = 4

n{P} only = 14-(2+3+2) = 7

n{M∩P∩Y} = 3

Number of women in the group = 6+4+7+(1+2+2+3) as above =25 women.


  1. If {(a2b-3c)3/4/a-1b4c5} = apbqcr; what is the value of p+2q?



A. (5/2)

B. -(5/4)



C. -(25/4)

D. -10

Correct Answer: Option D

Explanation

Hint: Use BODMAS and algebra to arrive at the values of P = 5/2, q = -25/4 and r = -9/2.Then substitute the values of p and q into p+2q to get -10.


  1. A trader bought 100 oranges at 5 for N1.20, 20 oranges got spoilt and the remaining were sold at 4 for N1.50. Find the percentage gain or loss.



A. 30% gain

B. 25% gain

C. 30% loss

D. 25% loss

Correct Answer: Option B

Explanation

Cost price (cp) = (100/5) x N1.20 =N24.00

Selling price (sp) = 100-20 = 80

(80/4) x N1.50 = N30.00

Gain = SP-CP = N30.00-N24.00 = N6.00

Gain% = (gain/CP) x 100 = 25%

A. 8/5

B. 8/3

C. 72/25

D. 56/9

Correct Answer: Option C

Let the common ratio be r so that the first term is 2r.

Sum, s = a/(1-r)

ie. 8 = 2r/(1-r)

8(1-r) = 2r, r = 8/5.

Sn = a(1-rn)/(1-r)

Solve further to get 72/25
