N15 000
N29 600
N27 800
N21 400
N35 000
Correct answer is E
Total yield = N3,700
Total amount invested = N 50,000
Let x be the amount invested at 6% interest and let y be the amount invested at 8% interest
then yield on x = \(\frac{6}{100}\) x and yield on y = \(\frac{8}{100}\)y
Hence, \(\frac{6}{100}\)x + \(\frac{8}{100}\)y
= 3,700.........(i)
x + y = 50,000........(ii)
6x + 8y = 370,000 x 1
x + y = 50,000 x 6
6x + 8y = 370,000.........(iii)
6x + 6y = 300,000........(iv)
eqn (iii) - eqn(2)
2y = 70,000
y = \(\frac{70,000}{2]\)
= 35,000
Money invested at 8% is N35,000
