450*4.5/100=20.25
20.25*4=81(from option)
20.25*4=81(from option)

(100*81/450*4.5)=(2*81/9*4.5)=(2*2/4.5)
so 4/4.5=4 (given ans)but
4/4.5=0.8888
So my doubt is how the ans was 4 years? can anyone explain me clearly?

1. T = S.I x 100/p x r
2. 81 * 100/4.5 * 450
3. if you simplify it 4 comes as the answer.
2. 81 * 100/4.5 * 450

The formula is i=ptr/100
p=450
t=?
r=4.5
i=81
then
t=100i/pr
t=(100*81)/450*4.5)
t=4 years
p=450
t=?
r=4.5
i=81
then
t=100i/pr
t=(100*81)/450*4.5)
t=4 years

t=(100*81)/(450*4.5)
t=(2*9)/4.5
t=18/4.5
y=1800/450=4 years.
So, lets dived them as 1800/450 = 4 years.
Bcoz if you want to convert decimal into number just put that much zeros same as above number here in 4.5 we convert it into 450 so just put two zeros above also bcoz from fraction point we increase 2 no. so 2 zeros are der.
Best of luck

SI=PTR/100
81=450*4.5*x/100
81=9*4.5
=4.05/81
=4 years
81=450*4.5*x/100
81=9*4.5
=4.05/81
=4 years

@Raghu.
We know that I= PTR/100
He gave I=81, p=450, R= 4.5 we have to find time (T)=?
T=100*I/PR
(100*81)/(4.5*450)= 8100/2025= 4 years got it.
