Answer (Detailed Solution Below)Option 3 : Rs. 25200/- Free Territorial Army Paper I - Full Mock Test 100 Questions 100 Marks 120 Mins Given: Time is 2 years Rate is 5% per annum The difference between simple interest and compound interest is Rs. 63. Concept: S.I = (P × R × T)/100 C.I = P[(1 + r/100)n - 1] Here, n is the number of terms in the year Calculation: Let sum be Rs. P Now, The simple interest for 2 years at 5% per annum is (P × 5 × 2)/100 ⇒ P/10 Now, The compound interest for 2 years at 5% per annum is P[(1 + 5/100)2 - 1] ⇒ P[(21/20)2 - 1] ⇒ P[(441/400) - 1] ⇒ 41P/400 So, The difference between Compound interest and simple interest is ⇒ 41p/400 - P/10 = 63 ⇒ 41P - 40P = 63 × 400 ⇒ P = Rs. 25200 ∴ The required sum of money is Rs. 25200. Shortcut Trick The difference between compound interest and simple interest for 2 years is ⇒ P(r/100)2 According to question ⇒ P(5/100)2 = 63 ⇒ P × 1/400 = 63 ⇒ P = 63 × 400 ⇒ P = 25200 ∴ The required sum of money is Rs. 25200 Latest Territorial Army Updates Last updated on Sep 22, 2022 The Territorial Army has released the official notification for Territorial Army Exam 2022.
