- 20%
ExplanationA 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% - 1. 20% of a man's salary is paid as rent, 60% are his living expenses and 10% are his savings. If he spends remaining 30 on the education of his children, find his salary

Correct Answer: 300
Correct Answer: 97500
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: 36 percent
Correct Answer: 30.56 percent
Correct Answer: Rs. 1400
Explanation:
Money lent at 9% = x
Money lent at 7% = (2600 ? x)
? 9x/100 + (2600 ? x) X 7 /100 = 206
? 9x + 18200 ? 7x = 20600
? 2x = 2400
? x = 1200
Money lent at 7% = 2600-1200 = 1400
Correct Answer: 17500
Explanation:
Let total number of votes enrolled = x
No. of voted cast = 70% of x = 0.7x
Valid votes = 98% of 0.7x
? 60% of total valid votes = 7203 = 60% of 98% of 0.7x
? 0.6 X 0.98 X 0.7x = 7203
? x = 7203 / (0.6 X 0.98 X 0.7)
? x = 17500
