(B) 100
(C) 1000
(D) 10000

Answer 1

- Hint: The basic S.I (International System of units) unit of mass is kilogram (kg) and is most commonly used in our daily life.

Complete step-by-step solution -

To answer this question, we have to understand what is mass and what are its units. All the measurement units for any object have been standardized and is categorized under S.I (International System of units) and CGS (Centimetre-Gram-Second) System.
A mass is defined as a characteristic of a physical body and the estimate of its resistance to acceleration when a total force is applied. According to S.I(International System of units) standard, the basic unit of mass is kilogram(kg).
A kilogram is expressed by considering the constant numerical value of Planck constant, h. The value of the constant h is $6.62607015 \times 10^{-34}$ Js (Joule-second). A kilogram is also defined as the mass of one litre of water.
A quintal is also called a center and is also a unit of mass in many countries like France, Portugal and Spain. In British English, one quintal is called a hundredweight and in American English, it refers to 100 kilograms. In India, the 100 kilogram that is 1 quintal is a standard measure of mass for agricultural products.
So, we can tell that one quintal is equal to 100 kilograms. In the reverse way, we can convert kilogram to quintal. This conversion is shown below.
\[\text{1kg=}\dfrac{1\text{quintal}}{100}=0.01\text{quintal}\],
Hence, one kilogram is equal to 0.01 quintal and 1 quintal is equal to 100 kilograms.

Note: The basic unit of mass is always kilogram and can be converted to higher units of measurement based on the quantity and for simplicity to quintal. It is must to remember that a quintal comprises 100 kilograms.
