Q 1 ans. 82
3 * 12 = 36
528 – 36 = 492
492 / 2 = 246
246 / 3 = 82
Q2 ans. 80 cents
10 * 20 = 200
600 – 200 = 400
400 / 5 = 80
Q 3 ans. 15.45
13.00 – 9.00 = 4 hrs
4 hrs * 55km/hr = 220km
220/5 * 9 = 396km
4/9 * 396km = 176km
176km / 2 = 88 km/hr
88km/hr – 8km/hr = 80km/hr
220km / 80km/hr = 23/4 hrs
2hrs + 23/4 hrs = 4hrs 45min
11.00 + 4hrs 45mins = 15.45
