A sum of Rs.13000 is divided into three parts such that the simple interests accrued on them for two, three and four years respectively may be equal. Find the amount deposited for 4 years. Choose the correct choice:
A) 5000  B) 6000  C) 4000  D) 3000  E) 7000
Let the amounts be x, y, z in ascending order of value. As the interest rate and interest accrued are   same for 4 years 3 years and 2 years i.e. 4x = 3y = 2z = k.   L.C.M. of 4,3,2 = 12 So x:y:z: = 3000 : 4000 :6000   The amount deposited for 4 years = 3000   ANSWER:3000
