Description for Correct answer:
By using formula, Installment = \( \Large \frac{6450 \times 100}{4 \times 100+ \left(3+2+1\right) } \times 5 \) =\( \Large \frac{6450 \times 100}{4 \times 100+ \left(3+2+1\right) } \times 5 \) =\( \Large \frac{6450 \times 100}{430} \) Installment = Rs.1500 Hence value of installment= Rs.1500

What annual instalment will discharge a debt of ₹6450 due in 4 years at 5% simple interest ?
Let each instalment be y Then,
⇒ | y + | y × 5 × 1 | + | y + | y × 5 × 2 | + | y + | y × 5 × 3 | + y = 6450 | ||||||
100 | 100 | 100 |
⇒ | y + | y | + | y + | y | + | y + | 3y | + y = 6450 | ||||||
20 | 10 | 20 |
⇒ | 21y | + | 11y | + | 23y | + y = 6450 |
20 | 10 | 20 |
⇒ | 21y + 22y + 23y + 20y | = 6450 |
20 |
⇒ y = | 6450 × 20 | = ₹ 1500 |

Second method to solve this question : Here , A = ₹ 6450 , T = 4 years , R = 5%
Equal instalment = | A × 200 |
T[200 + (T - 1) × R] |
Equal instalment = | 6450 × 200 |
4[200 + (4 - 1) × 5] |
Equal instalment = | 6450 × 200 |
4 × 215 |
Equal instalment = | 6450 × 200 |
4 × 215 |
Equal instalment = | 6450 × 50 |
215 |
Equal instalment = ₹ 1500
What annual instalment will discharge a debt of 6450 Rs. due in 4 years at 5% simple interest? [A]1500 Rs. [B]1835 Rs. [C]1935 Rs. [D]1950 Rs.
1500 Rs. Let each instalment be x. Then, $latex \because \left ( x+\frac{x\times 5\times 1}{100} \right ) + \left ( x+\frac{x\times 5\times 2}{100} \right ) + \left ( x+\frac{x\times 5\times 3}{100} \right ) + x = 6450&s=1$ $latex => \left ( x+\frac{x}{20} \right )+\left ( x+\frac{x}{10} \right )+\left ( x+\frac{3x}{20} \right )+x = 6450&s=1$ $latex => \frac{21x}{20}+\frac{11x}{10}+\frac{23x}{20}+x = 6450&s=1$ $latex => \frac{21x+22x+23x+20x}{20} = 6450&s=1$ $latex => \frac{86x}{20} = 6450&s=1$ $latex => x = \frac{6450\times 20}{86} = 1500 Rs.&s=1$
Hence option [A] is correct answer.

Calculation:
Installment for first year = x
Installment for second year = 1.10x
Installment for third year = 1.20x
Installment for third year = 1.30x
Installment for final year = 1.40x
Total amount to be paid = (1 + 1.10 + 1.20 + 1.30 + 1.40) × x = 6450
∴ x = 6450 / 6 = 1075
