Fast short trick for calculation simplification in math subject

Now we are discus the second 2^nd type of short trick tutorial  for calculation simplification in math subject .these type of short trick is very helpful for bank exam and other competitive exam .because in bank SSC and other competitive exam solved the all question in very short time. So now how to increase the speed to solved the competitive exam question answer and complete the cut of target in exam. So used the short trick and clear the cut off in any competitive exam.

Question is

Option 1) 45867 2) 45789 3) 3755 4) 8262

So now simple all values convert in single digit

Step 1  The total    5+4+7+8+9 = 33 = 3+3= 6  Answer

Step2   The total     8+4+6+2 = 20 = 2+0= 2  Answer

Step 3   The total   2+8+2 = 12 =1+2= 3 Answer

Step 4   The total   7+4+2 = 13 = 4 Answer

And Now calculate main Answer    6 – 2 + 3 – 4 = 3  Answer

 

Now 2^nd step calculate the all option one by one and also convert in signal digit

• 45867 = 4+5+8+6+7 = 30 = 3+0= 3
• 45789 = 4+5+7+8+9 = 12+12+9 = 21+12=33=3+3= 6
• 3755 = 3+7+5+5 = 20 = 2+0 = 2
• 8262 = 18 = 1+8 = 9

Last Step

Compare the all option answer with question main Answer

3 = 3

That is last Answer     45867

Note: This trick used for given option and answer

 

 

More Example :

245 + 412-121=?

Option 1) 243 2) 456 3) 564  4) 536

245 + 412 – 121 =?

11 + 7- 4

2+7-4 = 9-4=5

Check Option :

243 = 2+4+3=9

465=4+6+5 = 11+4 = 15=6

564 = 10+6 = 16 =7

536 = 11+3 = 14 = 5

Answer 5 = 5

 245 + 412-121= 536
