Amount in 4 years = Rs. 224
Formula Used
Amount = Principal + n(Simple Interest) (where n = no. of years)
Calculation
Let the Principal be P
Amount in 2 years = Rs. 212
⇒ P + 2(S.I) = Rs. 212 ---(1)
Amount in 4 years = Rs. 224
⇒ P + 4(S.I) = Rs. 224 ---(2)
Subtract (1) and (2)
⇒ S.I = Rs. 6
Put the value of S.I in eq (1)
⇒ P + 2(6) = Rs. 212
⇒ P = Rs. 200
∴ The required answer is Rs. 200
