preferred number Explanation: Generally the product is manufactured in different sizes or models like a

company manufacturing motors in the the range 0.5 kw to 50 kw to suite

the needs of different customers. Preferred numbers are used to specify the

sizes of the product in the these cases. There are commonly used five

preferred number series. There are R5,R10 R20, R40 & R80 series .

For Example - According to R10 series , if a manufacturer wants to

introduced the models between 15 to 100 units, then his series will be like...
