For annuity due,

C = ₹ 20,000, n = 3, I = 0.1, (1.1)^–3 = 0.7513

Therefore, P = `square/0.1 xx [1 - (1 + 0.1)^square]`

= 2,00,000 [1 – 0.7513]

= ₹ `square`

The future amount, A = ₹ 10,00,000

Period, n = 20, r = 5%, (1.025)²⁰ = 1.675

A = `"C"/"I" [(1 + "i")^"n" - 1]`

I = `5/200` = `square` as interest is calculated semi-annually

A = 10,00,000 = `"C"/"I" [(1 + "i")^"n" - 1]`

10,00,000 = `"C"/0.025 [(1 + 0.025)^square - 1]`

= `"C"/0.025 [1.675 - 1]`

10,00,000 = `("C" xx 0.675)/0.025`

C = ₹ `square`

The Cost of Living Index Number by Aggregate Expenditure Method is same as

The Cost of Living Index Number by Aggregate Expenditure Method is given by ______

Calculate the Cost of Living Index Number for the following data.

Given the following table, find the Cost of living Index Number using Aggregate Expenditure Method by completing the activity.

Therefore, Cost of Living Index using Aggregate Expenditure method is

CLI = `(sum"p"_1"q"_0)/(sum"p"_0"q"_0) xx square`

= `square/square xx 100`

= `square`

Choose the correct alternative:

An unbalanced assignment problems can be balanced by adding dummy rows or columns with ______ cost

A ______ assignment problem does not allow some worker(s) to be assign to some job(s)

State whether the following statement is True or False:

To convert the assignment problem into maximization problem, the smallest element in the matrix is to deducted from all other elements

Find the assignments of salesman to various district which will yield maximum profit

For the following assignment problem minimize total man hours:

Subtract the `square` element of each `square` from every element of that `square`

Subtract the smallest element in each column from `square` of that column.

The lines covering all zeros is `square` to the order of matrix `square`

The assignment is made as follows:

Optimum solution is shown as follows:

A → `square, square` → III, C → `square, square` → IV

Minimum hours required is `square` hours
