Question 1 :
ReplyDelete100 % - 16 % = 84 %
Bicycle + $330 = 84%
20/ 100 x 100% = 20 %
Bicycle + $430 = 104 %
20% --> $100
2 % --> $10
16 % --> $80 #
Question 2 :
a) Car --> 60km/h
Van --> 75 km/h
1/2h --> Car travel 30km
75km-60km = 15km
Every hour, Van is 15km nearer to the car.
30km/ 15km = 2
Thus, in two hours, van will catch up with car 2 hours + 30min = 2h 30min #
b) 6.30pm --2 hour --- 4.30pm
Van left at 4.30 pm
Car left at 4 pm #
Question 8 :
First man --> 1/4+1 of total
Second man --> 1/5+1 of total
Third man --> 3/4+3 of total
Fourth man --> the rest
1/5 + 1/6 + 3/7
= 42/210 + 35/210 + 90/210
= 167/210
210/210 - 167/210 = 43/210
210 units --> $840
1 unit --> $4
43 units --> $4x 43 = $172 #
Hope its correct! :)
