a. K people got off and 7 got in
Number of people when bus leaves Taung=64-k+7=71-k
 
(ii).1/3 people got off. 1/3(71-k) got off. This means 2/3(71-k) people were left on bus. 3 more people got on
Total no. of people when bus leaves Sebele 2/3(71-k)+3 
 
b. Now 25 people on bus.
2/3(71-k)+3=25
2/3(71-k)=22
2(71-k)=22x3=66
(71-k)=66/2=33
K=71-33=38
Hence k = 38
 
c. When bus left Taung no of people=71-k=71-38=33
 
Hope this helps
