P = x
A = ₹ 1326
R = 5%
T = 6 years
SI = P*R*T/100
= x * 5 * 6 / 100
= 3x/10
To find P
1326 - x = 3x / 10
4x = 1326 * 10
x = 13260 / 4
x = ₹ 3315
Year when the sum doubles itself.
P = ₹ 3315
A = ₹ 6630
R = 5%
SI = A - P
= 6630 - 3315
= ₹ 3315
Y = 100 * SI / P * R
= 100 * 3315 / 3315 * 5
= 20 years
A = ₹ 1326
R = 5%
T = 6 years
SI = P*R*T/100
= x * 5 * 6 / 100
= 3x/10

= 100 * 3315 / 3315 * 5
= 20 years
