Answer:
7,500
Step-by-step explanation:
Let's call the total income of Hamza by 'X'.
First he spends 20% of his income, so the remaining value is:
X - 20% of X = X - 0.2X = 0.8X
Then, he spends 70% of the rest, so he spends 70% of 0.8X:
0.8X - 70% of 0.8X = 0.8X - 0.7*0.8X = 0.8X - 0.56X = 0.24X
If this remaining is equal to 1800, we have that:
0.24X = 1800
X = 1800/0.24 = 7500
His total income is 7,500.
Answer:
Hamza's total income is Rs. 7500
Step-by-step explanation:
Here we have 20% of income spent on rent
70% of the rest spent om household expenditure
We take the balance as Rs. 1800, therefore, we have
Therefore, we have 70% of (100 - 20) or 70% × 80% = 0.7×0.8 spent on household expenditure
Which is 0.56 or 56% spent on household expenditure
Therefore total percentage spent is 20+56 = 76%
balance percentage left is 24%
∴Amount saved is 24% which is Rs. 1800
Therefore we have 24% of Hamza's total income = Rs. 1800
Hamza's total income is therefore Rs. 1800 × 100/24 = Rs. 7500.
