A.
N32.00 -
B.
N320.00 -
C.
N420.00 -
D.
N1680.00
Correct Answer: Option B
Explanation
Let his assistant work for x days
∴ his master worked (x + 10) day. Amount received by master = 40(x + 10),
amount got by his assistance = 10x
Total amount collected = N2000.00
∴ 40(x + 10) + 10x = 2000
= 40x + 400 + 10x
= 2000
50x + 400 = 2000
50x = 2000 – 400
50x = 1600
x = (frac{1600}{50})
x = 32 days
