Question

Use the 'Third, Tenth and Tenth Rule' to calculate interest on:
(i) 600 @ 8% p.a. for 75 days​

Answer 1

Answer:

600×8 ÷ 75

= 64

as the formula

p×n×r/t= Interest.

therefore the answer is

64.

Answer 2

Answer:

9.87

Step-by-step explanation:

1) 600×8×75×2/100000 = 7.2

2) 7.20000/3 = 2.4

3) 2.4/10 = 0.24

4)0.24/10 = 0.024

5) [7.2+2.4+0.24+0.024] = 9.864

6) 9.864/10000 = 0.0009864

7) 9.864 - 0.00098 = 9.87
