Answer:

The interest is Rs 86400

Step-by-step explanation:

Principle= Rs 9000,Time= 146 days,Rate of interest= 25/2%

                                time=146/365=0.4 year, Rate of interest=12 1/2%

Interest= P*T*R/100

I=9000*146 days* 25/2%/100

  9000*4*12/100*10*2

I= Rs 86400

Answer:

₹450

Step-by-step explanation:

Formula=PRT/100

R=25/2

T=0.4 year

P=₹9000

After substituting,

(9000*25*0.4)/(100*2)

=(9000*25*4)/(100*2*10). ----<0.4 can be written as 4/10>

=(9*25*2)/1 ----<simplification>

=₹450
