Answer:
Let the required ratio be x : y : z. Then,
S.I. on x rupees for 6 years at 10% p.a. = S.I. on y rupees for 10 years at 12% p.a.
S.I. on y rupees for 10 years at 12% p.a. = S.I. on z rupees for 12 years at 15% p.a.
x : y = 2 : 1 and y : z = 3 : 2
=> x : y = 6 : 3 and y : z = 3 : 2
=> x : y : z = 6 : 3 : 2
Therefore the ratio of his investments is 6 : 3 : 2.
