Answer 1

Answer:

SI = PRT / 100

SI = P * 5 * 2 / 100

SI = P / 10

And

A = P * (1 + 5/100) ^ 2

A = P * (21/20) ^ 2

A = 441P / 400

CI = A - P

=> 441 P/400 - p

=> 441 P-400 P/400

=> 41 P/400

=> CI- SI = Rs 30

=> 41 P/400 - p/100 = 30

=> 41 P - 40 P = 30

=> P/100 = 30

=> P = 400 x 30

=> Rs 12000

.°. Sum is ₹12000.
