Answer:

3. Rs. 120.00

Step-by-step explanation:

Given,

An Interest of Rs. 120 accrued on Rs. 400 at  certain Rate in a certain time.

SI=PTR/100

here SI=120

P=400

Rate=R

time=T

120=400*R*T/100

R*T=30

The Interest  that accrues on Rs. 1600 at half the Rate in  half the time ....

Sum=1600

Rate=R/2

Time=T/2

SI=(1600*R/2*T/2)/100

SI=4*RT

SI=4*30

SI=120
