Solution (By Examveda Team)

Let the principal in each case = 100 units According to the question,

		1^st part	2^nd part	3^rd part
Principal	→	100_x6	100_x3	100_x2
Rate %	→	10	12	15
Time	→	6	10	12
Interest	→	60_x6	120_x3	180_x2

Interest Interest is same in each, so equal the interest.
Hence required ratio
= 600 : 300 : 200 of sum
= 6 : 3 : 2
