If the compound interest on a sum at the rate of 5% p.a. for 2 years is Rs. 328, then find simple interest of same amount for same year and same rate of interest.

Rs. 325 Rs. 326 Rs. 320 Rs. 322

Rs. 320

C.I. @ 5%pa for 2 years = 10.25% S.I. @ 5%pa for 2 years = 10% ATQ, ⇒ P × 10.25% = 328 ⇒ P × 1% = \(\frac{328}{10.25}\) = 32 ⇒ P × 10% = 32× 10 = 320
