The rates of simple interest in two banks A and B are in the ratio 5:4. A person wants to deposit hi

Surit Datta   9 years AGO

Rate of interest = 5x and 4x
let he invests Rs P in bank A
and Q in bank B
then,
(P*5x*1/2*100) = (Q*4x*1/2*100)
it's implies,
5P = 4Q
so,
P:Q = 4:5
so option 5
that's it.

Supriya Mondal   9 years AGO

From the question we can write,
Rate of interest of the bank A and B are 5x and 4x respectively.
let he invests Rs P in bank A and Q in bank B
then,
(P*(5x/100)*1/2) = (Q*(4x/100)*1/2)
so,5P = 4Q
so,P:Q = 4:5
so, option 5)4:5 is the right answer

To get the same interest from both the banks,
If you deposit 100 in Bank A then you should deposit 125 in Bank B.
i.e. 100:125 => 4:5

Since,
Simple interest = (P*R*T)/100
where,
P=principal
R=rate of interest per annum
T= time in years
So,
PA/PB = RB/RA
PA/PB = 4/5

A --> S.I = (A*0.5*5x)/100

As S.I of A and B are equal, By euating two equations above we get
A/B= 4/5

It is Simple by going as options:
5:4 is the ratios of interest percentages
so Interest is same take example as 4:5

and
(5*(1/2)*4)/100=1/10
so in above the interest is same
the options is 5

If amounts/deposits are p & q with rate of simple interest 5x & 4x respectively, then

let rate be r1 and r2
given r1/r2=5/4
and let deposites should be x1 and x2
as interest should be equal from both the banks and time is same for both the banks
so by formula i=(p*r*t)/100
so x1*r1=x2*r2
