Answer:

Step-by-step explanation:  According to the question

The principal = 600

Interest =  90

years = 2.5 years

we can write in 2.5 years like  24 + 5 months = 29 months

Rate = ?

We have to find out the rate of interest by the simple interest formula

SI =  P ×  R  × T  / 100

90 = 600 ×  R  ×  29 / 12 × 100

90 = 600 × R × 0.024166

90 = 14.5  × R

90 / 14.5 = R

6.20 = R

So the Rate of interest be 6.20 %

If the Rate of interest increased by 8% , then the new percent be 14.20 %.

We now that Principal is 600

Rate = 14.20 %

time = 29 /12

Simple interest is

SI =  P ×  R  × T  / 100

SI =  600 × 14.20  × 29 /12 × 100

SI = 600 × 14.20 × 0.02416

SI = 205 .84

The new interest be 205.8
