করিম একজন ১৮ বছরের ছেলে। তার হাতে তর্জনী আঙুল নেই। তার দুটি হাতে মোট কতটি আঙুল?
To solve this problem, let's analyze it step-by-step:

Step-1: Karim is a 18 years old boy. He has no index fingers in his hands. 

Step-2: We know a normal boy has total 5*2=10 fingers in both hands. Two of them are index fingers (1 in a hand). But, Karim has no index finger.

Step-3: So, total number of fingers in Karim’s both hand is 10-2 = 8

#Answer: 8 fingers
