A man saves 1/6 of his salary, spends 1/4 of the remainder on rent and rest on food. What fraction of his salary does he spend on food.
Ans :5/8
Answers
Answer:
5/8
Step-by-step explanation:
let the whole salary be represented by x
he saves 1/6x
the remainder of the salary being 5/6x
fraction spent on rent = 1/4 of 5/6x = 5/24x
to obtain fraction spent on food, we'd have to subtract the fraction for rent from the remainder of the salary after saving.
5/6x - 5/24x
solving this will result in 15/24x = 5/8x
Step-by-step explanation:
let x denote the salary.
Since saving is 1/6 of the salary,
saving = 1/6x
Since rent is 1/4 of the remaining salary,
rent = 1/4(x - 1/6x) = 1/4x - 1/24x = (6x-x)/24 = 5x/24
Since food is the remaining( that is after saving and paying rent),
food = (x - 1/6x - 5x/24) = (24x - 4x - 5x)/24 = 15x/24
Therefore,
x = saving + rent + food
x = 1/6x + 5x/24 + 15x/24 - - - - - (1)
So,
food = 15/24 * x
food = 15/24 * (1/6x + 5x/24 + 15x/24) using (1)
food = 15/24 * (x)
food = 15x/24
food = 5x/8 (simplying)
Hence for food 5/8 of x is spent.
