Answer:
Solutions:
money invested = ₹700
time period = 1 year
amount = ₹900
so,
amount = principal + interest
900= ₹(700 + interest)
interest = ₹( 900-700)
interest = ₹200
so,
interest = principal *time *rate /100
200= 700×1×rate/100
rate = (200/7)%
rate and time will be same!
interest = p×r×t/100
I = p× 200/7×1÷100
I = p×1/7
amount = p+I
1350 = p+(p/7)
1350= 8p/7
p= (1350×7)/8
principal = ₹1181.25
