let x be the principle amount.

(x*7*12)/100 - (x*4.5*12)/100=585

therefore,x=1950

Acc to question Sum ,P is same R= 12% in both case

Then Interest of Rs.585 will be the interest of the difference of time period= (7-4.5)= 2.5 years

Now, P = 100xSI/RT = 100×585/12×2.5

P = 100×585//30 = 1950

585=p*12*7/100 - p*12*4.5/100
solving for p, we get 1950

let the amount be'x'.
interest of 12%for 7,4.5 yrs.
(x*12*7)/100*(x*12*4.5)/100=585
ans:1950

option 4 i.e 1950
p*12*7 - p*12*4.5 = 58500
on solving this we get p=1950

Here difference of interest=585
N=7 R=12
N2=4.5 R2=12
ie SI1 - SI2=585
SI1=( P * N * R ) / 100
SI2=( P * N2 * R2 ) / 100
SI1 - SI2=( P * N * R ) / 100-( P * N2 * R2 )/100
Taking common term P/100 outside we get
SI1 - SI2=P( N * R - N2 * R2 )/100
585 =P(7 * 12 - 4.5 * 12 ) / 100
=P ( 84 - 54 ) /100
585 * 100 = 30 P
58500 / 30= P
Therefore answer is
Option 4) 1950
585=P/100

we know simple interest si=(ptr)/100.
in first case let p=x,t=7 and r=12
in second case p=x and given t=4.5,r=12
so (x*7*12)/100=(x*4.5*12)/100
=>30x=585*100
=>x=1950
