ब्याज दर = 10% (per annum)
भिन्नात्मक मान = 10% = 1/10
∴ मूलधन = 10; ब्याज = 1
इसलिए, कुल किस्त = 10 + 1 = 11
समय सीमा | मूलधन |
प्रति वर्ष समान किश्त |
1st year | 10 × 11 = 110 | 11 × 11 = 121 |
2nd year | 102 = 100 | 112 = 121 |
कुल मूलधन = 110 + 100 = 210 |
इसलिए, 210 → 4620 रूपये
∴ 121 → (4620/210) × 121 = 2662 रूपये
∴ प्रत्येक किस्त (रुपये में) 2662 रुपये है।
Alternate Method
दिया गया है:
मूलधन = 4620 रूपये
ब्याज दर = 10%
किश्तों की कुल संख्या = 2
प्रयुक्त अवधारणा:
किश्त = \(\frac{P}{\left(\frac{100}{100+R} \right)+\left(\frac{100}{100+R} \right)^n}\)
जहाँ, P = मूलधन; R = ब्याज दर; n = किश्तों की संख्या
गणना:
किश्त = \(\frac{4620}{\left(\frac{100}{100+10} \right)+\left(\frac{100}{100+10} \right)^2}\)
= 4620/[(10/11) + (10/11)2]
= 4620/[(10/11) + (100/121)]
= 4620/(210/121)
= 4620 × (121/210)
= 2662
∴ प्रत्येक किस्त (रूपये में) 2662 रूपये है।
