Answer 1

Answer:

23805

Step-by-step explanation:

The law is interest, I=Pnr here p is main amount, n is year and r is rate of interest.

so r=I/Pn

here I is 29500-25000= 4500 Rs.

P is 25000 Rs and n is 3 years.

So r=(4500/25000x3) x100% = 6 %

The rest is easy..

here p is 20700, n is 2 and half years or 2.5 years, r is 6 %

so Interest, I = Pnr =20700x2.5x6% = 3105 Rs

then, total amount is ( main amount+interest) = 20700+3105 = 23805 Rs
