Solution

The correct option is D
Rs. 12093.75
12093.75 रुपए

At 25% interest, the invested amount becomes P(1+25100)=1.25P

1st year:

Rs. 14000 after calculating interest =14000×1.25=Rs.17500

After repaying Rs. 4000, he owes 175004000=Rs.13500

2nd year:

Principal amount for second year =Rs.13500

After calculating interest =13500×1.25=Rs.16875

After repaying Rs. 4000, he owes 168754000=Rs.12875

3rd year:

Principal amount for second year =Rs.12875

After calculating interest =12875×1.25=Rs.16093.75

After repaying Rs. 4000, he owes 16093.754000=Rs.12093.75


25% ब्याज पर, निवेश राशि हो जाती है P(1+25100)=1.25P

पहले वर्ष ;

रुपये 14000, ब्याज की गणना के बाद =14000×1.25=17500 रुपये.।

4000 रुपये चुकाने के बाद, बकाया राशि 175004000=13500 रुपये।

दूसरे वर्ष:

द्वितीय वर्ष के लिए मूलधन = रु। 13500

ब्याज की गणना के बाद =13500×1.25=16875 रुपये।

4000 रुपये चुकाने के बाद, बकाया राशि 168754000=12875 रुपये।

तीसरे वर्ष:

द्वितीय वर्ष के लिए मूलधन =12875 रु।

ब्याज की गणना करने के बाद =12875×1.25=16093.75 रुपये।

4000 रुपये चुकाने के बाद, बकाया राशि 16093.754000=12093.75 रुपये।
