Question

find the time when
principal= ₹5000, amount=₹6450 And rate=12%p.a​​

Answer 1

Answer:

Amount= P+s.i

s.i= 6450-5000=1450

now

s.i=P×R×T÷100

T=s.i×100/P×R

T=145000÷60000

T=2.41 years

Answer 2

S.I.=A-P

RS( 6450-5000)

rs. 1450

S.I.= P×R×T/100.

=1450= 5000×12×x/100

=1450×100= 5000×12×x

= t= 1450×100/ 5000 × 12

= x =2,5/12

(2 whole 5 by 12 ).=Time.
