Question:

What annual installment will discharge a debt of total amount ₹6450 in 4 years at 5% simple interest ?

Options:

₹1350

₹1500

₹1470

₹1605

Correct Answer:

₹1500

Explanation:

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
