A Certain Sum Of Money Amounts To Rs.1300 In 2 Years And To Rs. 1525 In 3.5 Years. Find The Sum And The Rate Of Interest?

Answer»

1525-1300= 225 for 1.5 yrs (3.5-2)

so for one yr 225/1.5= 150

then for 2 yrs INTEREST is 150+150=300

Then PRINCIPAL 1300-300=1000.

Now 150/1000*100= 15%.

1525-1300= 225 for 1.5 yrs (3.5-2)

so for one yr 225/1.5= 150

then for 2 yrs interest is 150+150=300

Then principal 1300-300=1000.

Now 150/1000*100= 15%.
