If N2,500.00 amounted to N3,50.00 in 4 years at simple interest, find the rate at which the interest was charged

A.

5%

B.

7\(\frac{1}{2}\)%

C.

8%

D.

10%

Correct answer is D

A = 3,500, P = N2,500

A = P + I

But I = N3,500 - N2,500

I = N1,000

I = \(\frac{PRT}{100}\)

N1,000 = \(\frac{2.500 \times R \times 4}{100}\)

1000 = 100R

R = \(\frac{1000}{100}\)

= 10%

Mr. Manu travelled from Accra to Pamfokromb a distance of 720km in 8 hours. What will be his speed in m/s?

A.

25m/s

B.

150m/s

C.

250m/s

D.

500m/s

Correct answer is A

\(\frac{720 \times 1000}{8 \times 60 \times 60}\) = \(\frac{20 \times 10}{8}\)

= \(\frac{200}{8}\)

= 25 m/s

The nth term of a sequence is Tn = 5 + (n - 1)2. Evaluate T4 - T6

A.

30

B.

16

C.

-16

D.

-30

Correct answer is C

T4 = 5 + (4 - 1)2; where n = 4

= 5 + (3)2 = 5 + 9

= 14

T = 5 + (6 - 1)2

where n = 6

= 5 + (5)2

= 5 + 25 = 30

T4 + T6 = 14 - 30

= -16

In 1995, the enrollment of two schools X and Y were 1,050 and 1,190 respectively. Find the ration of the enrollments of X and Y

A.

50:11

B.

15:17

C.

13:55

D.

12:11

Correct answer is B

Divide cash enrollment by their common factors then the answer of each division gives the required ratio. i.e. x = \(\frac{1050}{70}\) = 15

and y = \(\frac{1190}{70}\) = 17

ratio of enrollment of x to y = 15:17
