  • Digital multimeters have numeric displays and are more efficient than analog multimeters.
     

Components of a digital multimeter:

1.) Attenuator: It provides the power to the multimeter for the measurement of the required electrical quantity.

2.) ADC: The analog to digital converter is used to convert analog input to required digital output.

3.) Display: It is used to display the output in digital or numeric form.

4.) Recording mechanism: It is used to record the electrical quantities which are being by the multimeter.

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?
