Question

Ibrahim bought some flour. After using 1.5 kg of the flour to bake a cake
and 4/9 of the remainder to bake cookies, he was left with 1/3 of the flour he
had bought. How much flour did Ibrahim buy? (Give your answer in kilograms)

Answer 1

Let x be the flour in kilograms, Ibrahim had bought.
From the given data,
1.5 + 4/9x + 1/3x = x
1.5 + 4/9(x-1.5) + 3/9x = x
1.5 * 5/9 = 2/9X
x = 3.75
Therefore,
Ibrahim bought 3.75 kilograms of flour.
