Here comes a killer puzzle asked in IIM 9999=4 8888=8 1816=3 1212=0 1919=? Let's see who can crack this one... Pls ans with reason I'll check who got the answer! And i have a gift waiting for you.
Im probably making it a lot more complicated than it has to be. Perhaps you only have to count the number of closed regions in the digits... Which would make the answer 2? ?
