What sum of money will have to be invested and for how many years, in order to get simple interest of Rs 10,000 at the rate of 10 p.c.p.a.? (Write three pairs of values for P and N.)

Given: simple interest (SI):= Rs. 10,000, Rate of Interest (R) = 10% and Number of years (T) = ?, Principal (P) = ?

As simple interest (SI):




⇒ PT = 100000


Now,


(i) If P = 50000 then T = 2year


(ii) If P = 20000 then T = 5year


(iii) If P = 10000 then T = 10year
