What annual installment will discharge a debt of total amount ₹6450 in 4 years at 5% simple interest ? |
₹1350 ₹1500 ₹1470 ₹1605 |
₹1500 |
Let each installment be x, then ⇒ x + {x + \(\frac{x × 5 × 1}{100}\)} + {x + \(\frac{x × 5 × 2}{100}\)} + {x + \(\frac{x × 5 × 3}{100}\)} = 6450 ⇒ \(\frac{5x}{100}\) + \(\frac{10x}{100}\) + \(\frac{15x}{100}\) + 4x = 6450 ⇒ \(\frac{430x}{100}\) = 6450 ⇒ x = 1500 |
