উত্তর: TK. 100,000

Let the amount deposited at 8% and 10% interest be X and (120000 - X) respectively. Interest, I = P n r Now, X × 1 × 8/100 + (120000 - X) × 1 × 10/100 = 10000 [total interest] 8X + 10(120000 - X) = 1000000 [multiplying both sides by 100] or, 8X + 1200000 - 10X = 1000000 or, 10X - 8X = 1200000 - 1000000 or, 2X = 200000 So, X = 100,000 TK
