In what time will ₹7500 amount to ₹8625, if Simple Intrest is reckoned at
$7 \ \frac{1}{2} \%$
per annum

​

Answer 1

Answer:

T = 2 year's

Step-by-step explanation:

here

principle( P ) = 7500

Total Amount ( A ) = 8625

rate of intrest ( R ) = 7( 1/2 )% = 15/2

find [T]=time

we know that

I = PTR/100...............[R]

I = intrest

= total amount - principle amount

= 8625 - 7500 = 1125

put the values in equation [R]

1125 = ( 7500 × T × 15/2 )/100

1125 = ( 7500 × 15T )/200

1125 = [ 75 × 15T ]/2

1125 × 2 = 75 × 15T

2250 = 75 × 15T

2250/75 = 15T

30 = 15T

T = 2 year's.
