In order to prepare Xiaoying's tuition fee 15000 yuan for going to college six years later, her parents have now participated in the education savings. There are two ways to save: (65,438+0) save a 3 first. [Hint] The principal of the two savings methods can be calculated by the principal and interest calculation formula and the interest calculation method respectively, and interest = principal × number of periods × interest rate.

Sum of principal and interest = principal+interest.

Solution: Suppose you start saving X yuan. If you follow the first saving method, there are

x( 1+3.24%×3)( 1+3.24%×3)= 15000，

The solution is x≈ 12500.

If you follow the second saving method, there are

x( 1+3.60%×6)= 15000，

The solution is x≈ 12336 (yuan).

Because 125000 >: 12336,

Therefore, the second way of saving starts with less principal.
