Simple interest=PNR/100
P=amount in RS; N=number of years; R=interest rate in%
coming to the problem, Here
case1 interest=case2 interest
18000×1×R/100=P×0.75×R/100
(pls note 8months =0.75 years)
18000×1=P×0.75
18000=P×0.75
18000÷0.75=P
24000=P

in order to verify,
consider interest rate of 12% per year
case1 interest = 18000×1×12/100=2160RS
case2 ineterst=24000×0.75×12/100=2160RS
so by paying 24000 for 8 months we can get 2160RS which is the same interest we get when we pay 18000 for 12 months .
