A) 9000 B) 5000 C) 14000 D) 7000 E) 6000
Let the amounts be x, y, z in ascending order of value. As the interest rate and interest accrued are same for 3 years 6 years and 7 years i.e. 3x = 6y = 7z = k.   L.C.M. of 3,6,7 = 42 So x:y:z: = 14000 : 7000 :6000   The amount deposited for 6 years = 7000   ANSWER:7000
