The turnover of a store in February was 500,000 yuan, which decreased by 30% three months after the Spring Festival, and increased in April compared with March. In May, the growth rate increased by 5 percentage points (that is, the growth rate in May should be 0.05 higher than that in April), and the turnover reached 483,000 yuan. Find out the growth rate in April and May.

The quantity in March is: 50*[ 1-30%]=35.

Let the growth rate in April be X, then the growth rate in May is X+0. 05

35*( 1+X)*( 1+X+0 .05)=48。 three

Solution: X=0. 15

That is, the growth rate was 15% in April and 20% in May.
