Question

If I have 12 balls and I lose half of them, then I retrieve
2/3 of my lost balls, how many balls do I have ?​

Answer 1

Answer: 10. If I have 12 balls and I lose half of them, then I retrieve

2/3 of my lost balls, I'll be left with 10 balls.

Explanation: I've 12 balls.

I lost half of them i.e. 0.5×12 = 6.

Total - lost = 12- 6 = 6.

I retrieve 2/3 of lost balls i.e 2/3 × 6 = 4.

I already was left with 6 balls & I retrieved 4 balls. Hence, in total I've 6+4 = 10 balls.

I'll be left with 10 balls in the end.
