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
