Correct Answer: 33.33 percent
Correct Answer: 36 percent
Correct Answer: ? 22,500
Explanation:
Let the monthly income be x
Kritika spends 30% of her income on house rent. The remaining amount will be 70% of x
Kritika spends 60% of the rest (70% of 60% = 42% of x )on household expenditure. The remaining amount will be 28% of x
If 28% of x is 6300 then 100% will be 22,500
Correct Answer: 97500
Correct Answer: 300
Correct Answer: 20%
Explanation:
A man's average monthly expenditure for the first four months of the year = Rs.231.25.
For four month = 231.25 * 4 = Rs. 925
For next five month he spend = 231.25 + 22.75 for one month.
In five month he spend = (231.25 + 22.75) X 5 = 1270
If the person spent Rs. 605 in all during the remaining three months of the year,
Total expense = 925+1270+605= 2800
Saving = 3500-2800 = 700
% saving = 700/3500 * 100 = 20%
