How we can calculate the two number nearest to 100,200,300,...?
STEP 1 :
First we will take a BASE VALUE like '900'
STEP 2 :
Now we will take two values nearest to '900'
VALUE ONE - '906' VALUE TWO - '905'
STEP 3 :
Now we have to compare VALUE ONE and VALUE TWO from '900' and find out how much VALUE ONE and VALUE TWO differ from the BASE VALUE.
process to find difference
Subtract '906' and '900' to get DIFFERENCE VALUE ONE : '6'
Subtract '905' and '900' to get DIFFERENCE VALUE TWO : '5'
STEP 4 :
After getting difference values, Now we will multiply the difference values '6' and '5' to get SUB VALUE ONE: '30'
STEP 5 :
After getting SUB VALUE ONE now we will find the SUB VALUE TWO by adding '906' to '5'
'905' to '6'
We will get the same result, So right now we are taking '906' and '5'
After Adding the above values we will get : '911'
Now we will multiply '911' with '9' which is the first digit of BASE VALUE '900'.
after multiplying '911' to '9', we will get SUB VALUE TWO : '8199'.
STEP 6 :
Now we will concatinate or join the SUB VALUE TOW and SUB VALUE TWO to get the FINAL value.
Join or concatinate '8199' to '30' we will get,
FINAL VALUE : '819930'
