Mark me as brainlist

Step-by-step explanation:

It is given that

Amount (A)=2782.50

Rate of interest for two successive years =5% and 6%

We know that

A = P(1+r/100)

n

Substituting the values

2782.50=P(1+5/100)(1+6/100)

By further calculation

2782.50=P×21/20×53/50

So we get

P=2782.50×20/21×50/53

Multiply and divide by 100

P=278250/100×20/21×50/53

P=2500

Hence, the principal is 2500.
