Maths Formulas for ICSE Class 10 Goods And Service Tax
Some Terms Related To Gst:
GST – Goods and Service Tax Before GST, there were 13 different indirect taxes in India. These 13 indirect , taxes are replaced by GST (Goods and Service Tax). GST is levised by the Central and State Government and provide for a single and streamlined process. GST is a common tax for goods and service. The tax will be implemented at every step of value creation.
CGST: The Central GST or CGST is tax collected by the Central, when the sales are within the.
SGST: The State GST or SGST is tax collected by the State, when the sales are within states. the states.
IGST: The Integrated GST or IGST is tax collected by the Central, when the sales are outside the states.
Rates of gst: The GST is levied on multiple rates from 0% to 28%. GST Council finalized a four GST tax structure of 5%, 12%, 18% and 28%. Presently Petroleum and Liquor for human consumption is exempted from GST. The GST Rates for different items are as below: IGST Rate = CGST Rate + SGST Rate.
If output GST is more than input GST, then GST Payable = Output GST (GST on sale) – Input GST (GST on expenses purchase). If input GST is more than output GST, then GST Credit = No GST to be paid.

Maths Formulas for ICSE Class 10 Arithmetic Progression
An arithmetic progression is a each term is derived from the preceding term by adding or subtracting a fixed number called the common difference “d” For example, the sequence 9, 6, 3, 0,-3,.. is an arithmetic progression with -3 as the common difference.The progression -3, 0, 3, 6, 9 is an Arithmetic Progression (AP) with 3 as the common difference.
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n – 1) d, where Tn nth term and a = first term. Here d = common difference = Tn – Tn-1
Sum of first n terms of an AP: S =(n/2) [2а + (n- 1)d]
The sum of n terms is also equal to the formula Sn=n/2(a+L) where 1 is the last term.
Tn = Sn- Sn-1, where Tn = nth term.
When three quantities are in AP, the middle one is called as the arithmetic mean of the other two. If a, b andc are three terms in AP then b = (a+c)/2.
