Question

The ratio of Juma’s and Akinyi's earnings was 5:3. Juma’s earnings rose to shilling 8400 after an increase of 12%. Calculate the percentage increase in Akinyi’s earning given that the sum of their new earnings was shilling 14100.
(b) Juma and Akinyi contribute all the new earnings to buy maize at shilling 1175 per bag. The maize was then sold at shilling 1762.50 per bag. The two shared all the money from the sales of the maize in the ratio of their contributions. Calculate the amount that Akinyi got.

Answer 1

1.12j = 8400
j = 7500

j/a = 5/3
a = 3/5 j = 4500

(14100-8400)/4500 = 1.267
so, Akinyi's money grew by 26.7%
