You'll have trouble with this question because if the amount is invested for only 7 months, then according to the table you'll only get interest at a rate of 2% p.a., not 3.5% p.a.
Maybe the table isn't used at all.
I = Prn
= 75000 x 0.035 x 7/12
= $1531.25
.: Total amount on maturity = 75000 + 1531.25 = $76531.25
