Calculate the interest to be paid at the end of 3 years ,if Hari borrowed Rs 30000 at 3% interest per year

2700

Step-by-step explanation:

Given data

Time= 3 years

Principal= 30000

Rate= 3%

The simple interest formula is given as

SI=PR/100

substitute

SI= 30000*3*3/100

SI= 270000/100

SI= 2700

Hence the Interest is 2700

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
