First question: P: The interest is 5/2 = 2.5% every six months. Therefore the annual rate is 1.025^2 - 1 = 1.050625 (or 5.0625%) Q: If the annual rate is R, then (1+R)^4 = 1.18 So R = (fourth root of 1.18) - 1 = 0.0422 (or 4.22%)

Second question: You have copied the question wrongly. The fixed overhead variance is 4,000 (not 14,000) If you go backwards from the actual profit, then the standard profit = 124,000 + 8,000 - 13,000 + 4,000 = 123,000 (The sales volume contribution variance is not relevant because you are asked for the standard profit on actual sales - not for the budgeted profit.)
