 <translate> Stream of consciousness rationale: For 6 months, Shara was able to return $10 x 6 = $60 to her brother. Since she already returned half of the money, then this means she currently owes her brother $60. Four months from now, she will be able to pay an additional $10 x 4 = $40. Thus, she will still owe her brother $60 - $40 = $20 four months from now.
The question and answer pair are described below. <yor> Ìdánilójú: fún oṣù mẹ́fà, Shara lè dá $10 x 6 = $60 padà fún arákùnrin rẹ̀.
