Kate had 120 beads less than Connie. Connie had 230 beads left after giving 80 beads to Kate. How many beads did they have altogether?

Beads at start:
Connie: 1 unit
Kate: 1 unit - 120

Beads in the end:
Connie 230 (after giving 80 to kate)

In order to find Connie at start, we add back 80.

230+80=310

Kate at start: 310 - 120 = 190

Total at start: 190 + 310 = 500

Hope that helps.

Hi,

In this case, the answer is 1kg.

The answer would be 3kg if \"he gave 2/3 of the remainder to his neighbor\".
