Question

Find the time in which the simple interest on Rs. 5650 at 12% per annum will be Rs. 1695.​

Answer 1

SImple interest (SI) = Rs. 1695

Principle (P) = Rs. 5650

Time (T) = 2 years 6 month = 2 years + 1/2 years = 5/2 years

Rate of Interest (R) = ?

Now SI = (P*R*T)/100

⇒ 1695 = (5650*R*5)/2*100

⇒ R = (1695*2*100)/5650*5 = 12%

Answer 2

HERE IS UR ANSWER :

Here Simple interest = Rs. 1695

So ; SI = PRT/ 100

1695= ( 5650× r ×2.5 / 100r ) = 1695005650×2.5 = 12%
