Note:- If a bar(-) is placed above the Roman numeral its value increases by 1000 times

V̅ = 5,000
II = 2000
XVI = 16, 000
X̅ = 10,000
XX XII = 20, 000 + 12 = 20012

I 1
V 5
X 10
L 50
C 100
D 500
M 1000

* Rules of Roman numbers system

  1. We can use one sign in one numbers at only two or three times

    Example:

    1. II = 2
    2. III = 3
    3. XX = 20
    4. XXX = 30
    5. CC = 200
    6. CCC = 300
    7. MM = 2000
    8. MMM = 3000
  2. If we use smaller sign before bigger sign then we get the Subtraction of that two number

    Example:

    1. IV = 4
    2. CM = 900
    3. IX = 9
    4. CMM = 1900
    5. XL = 40
    6. XIX = 19
  3. Every sign can de subtracted only From two bigger sign from that sing

    Example:

    1. X can be subtracted from L & C.
    2. C can be subtracted from D & M
  4. If we use smaller sign after bigger sign then that both sign gets added

    Example:

    1. VI = 6
    2. XV = 15
    3. CX = 110
    4. DC = 600
  5. We can’t write L & D sign at the left side of bigger sign than that number
  6. If we use bar on the sign than their value becomes 1000 times multiple of its original value

    Example:

    1. V̅ = 5000
    2. C̅ = 1,00,000

The metric system

Measures of length

10 Millimeters (mm) = 1 centimeters (cm)
10 Centimeters = 1 decimeters (dm)
10 Decimeter = 1 meter (m)
10 Meters = 1decameters (dam)
10 Decameter = 1 hectometers (hm)
10 Hectometers = 1 kilometers (km)
1 meter = 100 cm = 1000 mm
1 km = 1000 m

Measures of weight

10 milligrams (mg) = 1 centigram (cm)
10 centigrams = 1 decigram (dm)
10 decigrams = 1 gram (g)
10 grams = 1 decagram (dag)
10 decagrams = 1 hectogram (hg)
10 hectograms = 1 kilogram (kg)
1 gram = 1000 mg
1 kg = 1000 gm
100 kg = 1 Quintal
1000 kg = 1 tonne = 10 Quintals

Measure of Capacity

10 milliliters (mi) = 1 centiliters (cl)
10 centiliters = 1 deciliters (dl)
10 deciliters = 1 liters
10 liters = 1 deciliters
10 deciliters = 1 hectoliters
10 hectoliters = 1 kiloliters
1 liters = 1000 ml
1 kiloliter = 1000 liters

Jubilee Celebration

Anniversary = 1 Year
Decade = 10 Year
Silver Jubilee = 25 Year
Golden Jubilee = 50 Years
Diamond Jubilee = 60 Years
Platinum Jubilee = 75 Years
Centenary = 100 Years

Number Measures

1 Unit = 1
2 Units = 1 Couple
12 Units = 1 Dozen
12 Dozens = 1 Gross = 144 units
20 Units = 1 Score = 1 kori
12 Gross = 1728 units = 1 Great Gross

Paper measures

24 Sheets = 1 Quire
20 Quire = 480 Sheets = 1 Ream
500 Sheets = 1 commercial Ream

Gram System

10 milligram 1 centigram
10 centigram 1 decigram
10 decigram 1 gram
10 gram 1 decagram
10 decagram 1 hectogram
10 hectogram 1 kilogram
100 kilogram 1 quintal
1000 kilogram (10 quintal) 1 metrictone

Metric System

10 millimeter 1 centimeter
10 centimeter 1 decimeter
10 decimeter 1 meter
10 meter 1 decameter
10 decameter 1 hectometer
10 hectometer 1 kilometer
1 kilometer 5/8 mail
1 meter 39.37 inch
1 inch 2.54 cemi
1 feet 30.48 cemi

Sir I would like to say something, the practice test questions and part's of the maths are very very informative to us.
