39/100 is the simplest form
Answer:
The capacity of water in the tank is 300 litres
Step-by-step explanation:
Let the unknown capacity be x
4/5 of x-190 litres = 1/6 of x
4x/5-190 litres = x/6
Cross x/6 and 190 litres over the equation sign
4x/5-x/6 = 190 litres
The LCM is 30
(24x-5x)/30 = 190 litres
19x/30 = 190 litres
Cross multiply
190 litres*30 = 19x
5700 litres= 19x
Divide through by 19
x = 300 litres
The interest for each method will be:
- Previous Balance Method = $37.50
- Adjusted Balance Method = $36.88
- Average Daily Balance Method = $2966.67
<h3>How to calculate the interest?</h3>
The Previous Balance Method will be:
= PTR
= 3000 × (1/12) × 0.15
= $37.50
The Adjusted Balance Method will be:
P = 3000 - 50 = 2950
t = 1/12
r = 15% = 0.15
I = 2950 × (1/12) × 0.15
= $36.88
The Average Daily Balance Method will be:
= (3000 × 10) +(2950 × 20)/30
= 89000/30
= $2966.67
