Gyaan School₹1000 is invested at 10 percent simple interest. Check at the end of every year if the total interest amount is in A.P. If this is an A.P. then find interest amount after 20 years.
Print or SaveSol. Simple interest = \(P* R*N\over100\)
Simple interest after 1 year = \(1000 *10 *1\over100\) = 100
Simple interest after 2 year = \(1000 *10 *2\over100\) = 200
Simple interest after 3 year = \(1000*10 *3\over100\) =300
According to this the simple interest for 4, 5, 6 years will be 400,500 , 600 , respectively.
From this d = 100 and a = 100
Amount of simple interest after 20 years
tn= a+(n-1)d
t20= 100 +(20-1) 100
t20= 2000
Amount of simple interest after 20 years is = ₹ 2000
