Problem: Problem: on a sum of money , the simple interest for 2 years is rs . 330 , while the compound interest is rs . 340 , the rate of interest being the same in both the cases . the rate of interest is
Options: a ) 15 % , b ) 14.25 % , c ) 6.06 % , d ) 10.5 % , e ) 11.5 %
Solution: c
Explanation: "explanation : the difference between compound interest and simple interest on rs . p for 2 years at r % per annum = ( r a si ) / ( 2 a 100 ) difference between the compound interest and simple interest = 340 - 330 = 10 ( r a si ) / ( 2 a 100 ) = 10 ( r a 330 ) / ( 2 a 100 ) = 10 r = 6.06 % answer : option c"

Problem: Problem: a number with an interesting property : when i divide it by 2 , the remainder is 1 . when i divide it by 3 , the remainder is 2 . when i divide it by 4 , the remainder is 3 . when i divide it by 5 , the remainder is 4 . when i divide it by 6 , the remainder is 5 . when i divide it by 7 , the remainder is 6 . when i divide it by 8 , the remainder is 7 . when i divide it by 9 , the remainder is 8 . when i divide it by 10 , the remainder is 9 . it ' s not a small number , but it ' s not really big , either . when i looked for a smaller number with this property i could n ' t find one . can you find it ?
