Answer 1

Answer:

12958

Explanation:

let the principle be equal to X rupees

SI= X×8×2/100

=4/25X

A=P+SI

12122=X+4/25X

12122=25+4/25X

12122=29/25X

12122×25=29X

303050=29X

X=10450

thus principal is 10450

SI for 2 years is

10450×9×8/3×100

10450×24/3×100

209×8/1×1

2508

Amount for 2 years is

(10450+2508)

12958
