Question

if a person by his total income, he send 30% for home rent and remaining 40% he spent for others goods then remaining amount is 2100 rupees what is the total income​

Answer 1

Answer:

Let's assume income of X to be 100.

If X spends 20% on house rent, he will be left with 100*.8 = 80

Now out of 80 he spends 70%, so now he is left with 80*.3 = 24

Here 24 represents saved income of $1800 , then 100% represents 1800*100/24=7500.

So the total income is 7500.
