Question

James spent a quarter of his net salary on school fees. He spent a quarter of the remainder on electricity and water bills. He spent a nineth of what remained on transport. If he finally had sh.3,400, calculate a) His net January salary
b) Money spent on school fees
C) money spent on transport
d) money spent on electricity and water bills

Answer 1

fees: 1/4, leaving 3/4
utilities: 1/4 * 3/4 = 3/16, leaving 9/16
transport: 1/9 * 9/16 = 1/16, leaving 8/16 = 1/2
so now you know that if his salary is x, then 1/2 x = 3400
Now you can answer the questions.
