A certain sum is invested at simple interest at 18% p.a. for two years instead of investing at 12% p.a. for the same time period. Therefore the interest received is more by Rs. 600. Find the sum?
Answer/Solution
5000
Steps/Work
Let the sum be Rs. x.
(x * 18 * 2)/100 - (x * 12 * 2)/100 = 600 => 36x/100 - 24x/100 =600
=> 12x/100 = 600 => x = 5000.Answer:E
(x * 18 * 2)/100 - (x * 12 * 2)/100 = 600 => 36x/100 - 24x/100 =600
=> 12x/100 = 600 => x = 5000.Answer:E
