Question

The C.I on a certain sum for 2 years is 41 and S.I is 40.Then the rate per annum is?

Answer 1

Answer:

Step-by-step explanation:

cost price of 10 cycles=10x2400=24000 rs

selling price=(5x2200)+(5x2800)=25000

gain=sp-cp/cp*100=2 1/12%

Answer 2

For SI

In 2yr = 40

1 yr = 20

for CI

In 2 yr =41

1yr =20

Then for 2nd yr = 41-20= 21

The difference= 21-20 =1

Then,

%= 1/20 *100= 5%
