ATQ, Simple interest Sum rate of interest time period in years 100 So, simple interest earned a 1000 20 3 100 Rs. 0.6a 600 And compound interest earned a - 4000 1 20100 3 - a - 4000 a - 4000 1.728 - 1 a - 4000 0.728 Rs. 0.728a - 2912 So, two cases are possible Case I simple interest compound interest So, 0.6a 600 0.728a - 2912 1080 Or, 2432 0.128a So, a 19000 Case II simple interest compound interest So, 0.6a 600 1080 0.728a - 2912 Or, 4592 0.128a So, a 35875 For statement I Since, a can take two values So, statement I is true. For statement II Again, since a 19,000 or 35875 which are greater than 10,000 So, statement II is false. For statement III Since, a has multiple values So, statement III is false.

capital denoted as 'a + 1000' into a scheme yielding a straightforward interest rate of 20% per annum for a duration of three years. Simultaneously, 'A' ventured into a financial enterprise involving an amount 'a - 4000' invested in a compound interest scheme at a 20% annual rate for a three-year period.If the difference between interest earned from both investments is Rs. 1,080, Determine then which of the following statement(s) is/are true? I. The variable 'a' can take multiple values. II. The minimal admissible value for 'a' proves to be less than the grand threshold of 10,000. III. 'a' is compelled to be an integer of even number."

A Only I

B Only I and II

C Only II and III
