Answer:

I don't know it because I don't know how can we do it

Answer 2

Answer:

P=2000

Step-by-step explanation:

Amount=₹1740

Principal=₹1200

Interest=₹(1740-1200)=540

R=(540*100)/1200*5)=9%

let the principal be p

S.l=p×r×t/100

S.l= 9p/25

Now

Amount=Interest+principal

2720=9p/25p

2729×25=9p+25p

P=6800/34

P=2000

Therefore the principal is ₹2000
