Question
Jacob spends 8% of his income on transport and 60% of the remaining amount on food. After these expenses, he managed to save 1800 B. 1000 D. $1100
Solution
Let's solve this step by step:
-
We know that Jacob spends 8% of his income on transport and 60% of the remaining amount on food. After these expenses, he saves $662.4.
-
Let's assume Jacob's income is X.
-
After spending 8% on transport, he is left with 92% of his income. So, the amount he has after transport expenses is 0.92X.
-
He then spends 60% of the remaining amount (0.92X) on food. So, he is left with 40% of 0.92X, which is 0.4 * 0.92X = 0.368X.
-
We know that this remaining amount is 662.4.
-
To solve for X, we divide 1800.
So, Jacob's income is 1800.
