Solution
(i) Initial balance of student’s account = ₹ 690
Deposited amount = ₹ 485 (+)
∴ Amount left in the account = ₹ 690 + ₹ 485 = ₹ 1175
(ii) Balance in the account = ₹ 1175
Amount withdrawn = ₹ 500 (−)
Amount left = ₹ 1175 – ₹ 500 = ₹ 675
(iii) Balance in the account = ₹ 675
Amount withdrawn = ₹ 350 (−)
Amount left = ₹ 675 – ₹ 350 = ₹ 325
(iv) Balance in the account = ₹ 325
Amount deposited = ₹ 89 (+)
Amount left = ₹ 325 + ₹ 89 = ₹ 414
(v) Balance in the account = ₹ 414
Amount withdrawn = ₹ 300 (−)
Amount left = ₹ 414 – ₹ 300 = ₹ 114
