Understanding GST
Unlock Audio Lesson
Good morning, everyone! Today we will discuss Goods and Services Tax, or GST. It is an indirect tax on the supply of goods and services. Can anyone tell me what GST consists of?
Isn't there a Central GST and a State GST?
Exactly! The GST is split into CGST, which goes to the central government, and SGST, which goes to the state government, both charged at 50% when sales occur within a state. Now, what about sales that happen between states?
I think that would be the Integrated GST, or IGST!
Correct! IGST applies for inter-state transactions. Now, let’s use a quick memory aid. Remember GST as 'Good Services Tax', it can help you recall its coverage. What’s the formula for calculating GST?
Is it GST equals the Taxable Amount times the GST Rate?
Yes, fantastic! And what do you get when you add GST to the cost price?
You get the final price.
Exactly! Let’s summarize what we learned today: GST is an indirect tax split between CGST and SGST for intra-state, and IGST for inter-state sales with a straightforward formula for calculation.
Banking Concepts

Let’s shift gears and discuss banking. Today, we'll focus on Recurring Deposit Accounts, also known as RD accounts. Can anyone explain what an RD account is?
It's a savings account where you deposit a fixed amount every month.
Correct! It's a disciplined way of saving. Now, how do we calculate the total interest earned from an RD account?
Isn't there a specific formula for that?
Yes, and it's I = P × n(n + 1) × r / (2 × 12 × 100). Who remembers what the variables mean?
P is the monthly deposit, n is the number of months, and r is the annual rate of interest.
Right! If you remember 'Penny Notch Riddle' as P = Deposit, N = Month, R = Rate, it will help you recall the formula. Let’s look at an example for clarity.
Can we do it based on the ₹1,000 monthly deposit for 12 months at an interest rate of 8%?
That’s a great example! The interest would be ₹520, making the maturity value ₹12,520. Let’s recapture the key points: RD accounts accumulate interest based on fixed deposits, having a specific calculation formula.
Shares and Dividends
Unlock Audio Lesson
Our final topic today is Shares and Dividends. Can anyone define what a share is?
A share is a unit of ownership in a company.
Exactly! Now, what are face value and market value?
Face value is the nominal value of the share, while market value is the price it sells for in the market.
Correct! Let’s add to that, dividends are returns given to shareholders based on the share's performance. How do we compute dividends?
We multiply the dividend percentage by the face value!
Exactly! Remembering ‘Face Gives Demand’ as Face Value gives you dividends. Anyone knows how to figure out the yield of a share?
We divide the dividend by the market value and multiply by 100?
Yes! Let’s recap: Shares represent ownership, with face and market value defining their worth, and dividends being the returns based on those values. Excellent job today!

Examples
-
A shopkeeper sells goods for ₹15,000 with an 18% GST rate after purchasing them for ₹10,000. Input GST is ₹1,800, Output GST is ₹2,700, and the net GST payable is ₹900.
-
If a person deposits ₹1,000 monthly in an RD for 12 months at an 8% interest rate, they would earn ₹520 as interest, totaling a maturity value of ₹12,520.
-
If a ₹100 share sells for ₹120 and gives a 12% dividend, then the dividend would be ₹12, and the yield would be 10%.
