Question

P= RS 12000 A= RS 16500 T= 2 1/2 yrs. Rate percent per annum simple interest will be ?

Answer 1

Step-by-step explanation:

si=16500-12000

=4500

t=21/2

si=prt/100

4500=12000×r×21/2

4500=126000r

r=4500/126000

=

Answer 2

Answer:

given that,

P= 12000

A=16500

T= 2 1/2 = 2.5

Step-by-step explanation:

A-P=SI

16500- 12000=4500

SI= 4500

SI = PRT/ 100

substituting the values

12000 * R* 2.5/100 = 4500

30000*R/100=4500

300*R = 4500

R= 4500/300

r= 15%

Hope it helps you!!
