Answer 1

Answer:

Rs.10,000 I think it's helpful and pls make me brainlist

Step-by-step explanation:

Let the sum of money be ′x′ = Principal (P)

R=5%

T=2 years

C.I=P(1+100R)T−P

=x(1+1005)2−x

=400441x−x

=40041x

S.I=100PTR

=100x×2×5

=10x

ATP, 40041x−10x=25

40041x−40x=25

⇒x=10,000

Hence the sum is Rs 10,000
