If the interest rate of one-year fixed deposit of the bank is increased by 1.89%, the interest of one-year fixed deposit of 100000 yuan will be increased (after deducting 5% interest tax)______ Yuan

100000 yuan = 100000 yuan, 100000 × 1.89% × 1 × (1-5%), = 100000 × 0.0189 × 1 × 0.95, = 1795.5 yuan; answer: the additional interest is 1795.5 yuan
