Question

In how much time will 25,600 amount to RS 35,664, when money is worth 9 1/4% per annum simple interest?

Answer 1

HEY THERE!


$\bold{\huge{SOLUTION:-}}$


$\bf{Given;-}$


Amount (A) = 35,664

Principal (P) = 25,600

Simple Interest = Amount - Principal

$\: \: \: \:$ = 35,664 - 25,600

$\: \: \: \:$ = 10064

Rate = 37/4 %


$\bf{Method of Solution:-}$

We know that Simple Interest Formula!

Simple Interest = P×R×T/100

10064 = 25,600 × 37/4 × T /100

1006400= 6400×37×T

1006400 = 236800 × T

T = 1006400/236800


T = 4.25 Year!


Thus, Time Will be 4.25 Years.

Hence, Required Time Will be 4.25 years

Answer 2

In this question,

It is given that,

Principal (P) = Rs. 25600
Amount (A) = Rs. 35664
Rate (R) = 37/4 % p.a.
Time (N) =?
Now,
S.I = A-P
=> S.I = Rs (35664-25600)
=> S.I = Rs. 10064

Now,

S.I = PRN/100
=> S.I x 100/ PR = N
or,
=> N = S.I x 100/PR
=> N = 10064 x 100/ 25600 x 37/4
=> N = 10064 x 100 x 4/ 25600 x 37
=> N = (4025600/947200) Years
=> N = 4.25 Years
