Question

find the principal if A = 3250, T= 3 years, S.I =10%per annual​

Answer 1

Answer:

P=10830

Step-by-step explanation:

Let principal amount be x.

We know that ,

A=P×R×T/100

3250= x × 10 × 3 /100

x = 3250 × 100/10 × 3

x= 10830

Answer 2

Answer:

Let Principal be x.

therefore,

SI=3250-x

SI=P×R×T/100

THUS,

P=SI×100/R×T

x=(3250-x)×100/10×3

×=32500-10x/3

3x+10x=32500

13x=32500

x=32500/13

x=2500

Principal=2500
