साधारण ब्याज पर कोई राशि 2 वर्षों में Rs 13,440 और 5 वर्षों में Rs 16,800 हो जाती है। मूलधन क्या है?
Answer और ExplanationAnswer and explanation
Answer: (B) Rs 11,200
1
3 साल का interest 16,800 - 13,440 = 3,360 है, यानी सालाना simple interest 1,120 है।
2
2 साल का interest 2 x 1,120 = 2,240 होगा।
3
Principal = 13,440 - 2,240 = 11,200 है।
✓
उत्तर (b) Rs 11,200 है।
1
The 3-year interest is 16,800 - 13,440 = 3,360, so the yearly simple interest is 1,120.
2
Interest for 2 years is 2 x 1,120 = 2,240.
3
Principal = 13,440 - 2,240 = 11,200.
✓
The answer is (b) Rs 11,200.
