Many questions are asked in various examinations such as CAT, SSC CGL, SSC CHSL, SSC CPO, BANK PO, BANK CLERK, RAILWAY, LDC, etc., you can solve those questions very easily by digit sum in just 2-3 seconds. Digit Sum is a revolutionary concept and very useful for solving the questions pretty fast. The mathematical operation you do with question the same mathematical operation can be done with the DIGIT SUM of that question. In digit sum, we don’t count 9. Example- if there is a number 12345 and we have to get the square of it. So digit sum of 12345= 1+2+3+4+5=15=1+5=6 Square of the digit sum= (6)2=36=3+6=9 Now the digit sum of the square of 12345 will be 9. Lets check-(12345)2=152399025=1+5+2+3+9+9+0+2+5=36=3+6=9 In the given question (11111)2 the digit sum of the answer will be (1+1+1+1+1)2=25=2+5=7 Answer-123454321=(1+2+3+4+5+4+3+2+1)=25=2+5=7 Satisfies You can use DIGIT SUM not only in number system but also in every topic of maths like average, time and distance, percentage, and even mensuration too.
