Question

If rs 500 amounts to Rs 725 at 9% simple interest in sometime ,what will Rs 600amount to at 11% in same time?

Answer 1

Answer:

$Rs\ 930$

Step-by-step explanation:

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

step 1

Find the number of time periods t

in this problem we have

$t=?\ years\\ P=Rs\ 500\\ A=Rs\ 725\\r=0.09$

substitute in the formula above  and solve for t

$725=500(1+0.09t)$

$t=[(725/500)-1]/0.09$

$t=5\ years$

step 2

what will Rs 600 amount to at 11% in same time?

we have

$t=5\ years\\ P=Rs\ 600\\ A=?\\r=0.11$

substitute in the formula

$A=600(1+0.11*5)$

$A=600(1.55)$

$A=Rs\ 930$
