Answer» Correct Answer - Option 3 : A Given: Money becomes Rs. 1200 in 4 years Money becomes Rs. 1500 in 7 years Calculation: According to question Difference between the money of 7 years and 4 years = 1500 - 1200 ⇒ Rs. 300 So, Interest of 3 years = Rs. 300 Now interest of one year = 300/3 = Rs. 100 ⇒ Interest of 4 years = 4 × 100 ⇒ Rs. 400 Principal amount = 1200 - 400 ⇒ Rs. 800 ∴ The Principal amount is Rs. 800 |
