Question

kitne year Mai 1200rs ki Rashi 5% barshik ki sadharan byaj ki dar se 1800rs ho jayegi​

Answer 1

si=p×r×t/100

si= amount-principal

si =1800-1200

si=600

formula me rakhne par

1200×5×t/100=600

on simplyfying we get

12×5t=600

60t=600

t= 10

10 sal me rashi 1200 se badhkar 1800 ho jayegi

Answer 2

Answer:

10year

Let time = t year

now there's a simple formula Ptr/100 where p is principal r is rate and t is time

now 1200×5×t÷100=600 (as amount=1800 and principal =1200 so intrest =1800-1200=600)

or t = 10
