A sum of Rs.21000 is divided into three parts such that the simple interests accrued on them for three, four and five years respectively may be equal. Find the amount deposited for 5 years.	Choose the correct choice from the following answers.
A) 13000
B) 11000
C) 16000
D) 14000
E) 12000
Let the amounts be x, y, z in ascending order of value. As the interest rate and interest accrued are   same for 3 years 4 years and 5 years i.e. 3x = 4y = 5z = k.   L.C.M. of 3,4,5 = 60 So x:y:z: = 20000 : 15000 :12000   The amount deposited for 5 years = 12000   ANSW12000R:12000
