Tai Yee Long? Da Er Long? Loan shark?

I found 2 piece of these sticked on my shop this morning. This company offer 3 types of loan financing.

a)Borrow RM1,000 pay back RM1200 = 20 days x RM60.
Interest rate: 360%pa

b)Borrow RM1,000 pay back RM1200 = 4 weeks x RM300
Interest rate: 240%pa

c)Borrow RM1,000 pay back RM1200 = 3 months x RM 400
Interest rate: 80% pa

Ask the pharmacist
1) Is my calculation correct?
2) Who want to take option A? Even option C i also won't take.
Considering,
Base Lending Rate is 6.75%pa
Fixed Deposit is 3.7%
PTPTN loan is 3% pa
Share market is 10% or more
Selling pharmacy goods 10-25%

Giving out loan 80-360%?

Lesson learned:

a) Learn your maths.
b) If u want to borrow money from loan shark, try not to pay back soon. The longer the period, the lower the interest? hehe
c) Loan biz is a good biz. Profit Margin at least 20%. The customer will find u, not that u need to find customers. Just leave your contact around.
