Example 1
The graph below was used for converting Kenya shillings into Uganda shillings. Use it to answer
questions below
(a) If you had 1 Kenya shilling, how many Uganda shillings would you have got?
From the graph
K. shs 80 = Ug shs.1600
1600 𝑥 1
K shs 1 = 𝑈𝑔 𝑠ℎ𝑠. = 20
80
(b) How many Kenya shillings would one have got for Uganda shillings 1 400?
1400
Ug shs 1400= = K shs 70
20
Example 2
A blanket in Uganda costs 20,265 shillings. How much would the same blanket cost in Kenya shillings,
given that 1US dollar is Uganda shillings 965 and 1 US dollar is Kenya shillings 65?
Solution
Converting Uganda shillings to dollars
Ug. Shs 965 = 1 USD
20265
Ug. Shs 20,265 = USD = 21
965
Changing dollars to Kenya shillings
1 USD = K shs. 65
∴ 21 USD = K shs. 65 x 21 = Ksh. 1, 365
