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

Now 2nd 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

3 = 3

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
