SI=

$\frac{ptr}{100}$

$\frac{6400 \times 14 \times 4}{100} = 3584$

The amount is (3584+6409)=9984

Answer 2

Answer:

4102.5

Step-by-step explanation:

take principal as x

si=p×r×t /100

x×14×4/100 =56x/100

amount =6400

6400=x+56x/100

6400=100x+56x/100

640000=156x

x=640000/156

reduce...

then you will get 115000/39

divide . then you will get the ans 4102.5
