P=1250 R=21/2 T=11/2 S.I=?

1.	P=1250 R=21/2 T=11/2 S.I=?
Answer» Step-by-step explanation: Simple Interest, S.I. = RS. 1260 = 100 PR×2 = 50 PR -(i) COMPOUND Interest, C.I. = AMOUNT(A) - Principle(P) =P(1+ 100 R ) 2 - P = PR(R/10000+1/50)=Rs.1323 -(ii) Dividing (ii) by (I), 200 R +1 = 1260 1323 ⇒Rate,R=10%p.a. Now, 100 PRT =1260 ⇒ 100 P×10×2 =1260 ⇒ Principal or Sum , P = Rs.6,300

Answer»

Step-by-step explanation:

Simple Interest, S.I. = RS. 1260 =

100

PR×2

-(i)

COMPOUND Interest, C.I. = AMOUNT(A) - Principle(P)

=P(1+

100

)

- P = PR(R/10000+1/50)=Rs.1323 -(ii)

Dividing (ii) by (I),

200

+1 =

1260

1323

⇒Rate,R=10%p.a.

Now,

100

PRT

=1260

⇒

100

P×10×2

=1260

⇒ Principal or Sum , P = Rs.6,300
