Answer 1

Answer:

Amount = ₹7234.5

C.I = ₹ 734.5

Step-by-step explanation:

P= ₹6500

r1%= 5%

r2%= 6%

T= 2 yrs

A= p*(1+r1/100*1+r2/100)

Amount= 6500*105/100*106*100

Amount = 6500*21/20*53/50

Amount = 13*21*53/2

Amount = ₹7234.5

C.I = ₹734.5

Answer 2

Answer:

734.5

Step-by-step explanation:

P= 6500 R1=5% R2=6% T=n

Formulae for Interest is

I = (P*R*T)/100

SO, by this interest for 1yrs is where P=Rs.6500, R1=5% and T=1

I=Rs. 325

A=I+P

A=6500+325

A=Rs.6825

and, interest for 2nd year with P=Rs.6825, R2=6% and T=1yrs

I=Rs.409.5

Final Amount= 6825+409.5

= Rs.7234.5

And total C.I=325+409.5

=Rs.734.5
