1. A man spends 35% of his income on food, 25% on children's education and 80% of the remaining on house rent. What percent of his income he is left with?


(a) 8%


(b) 10%


(c) 12%


(d) 14%


ANS: 35% + 25% = 60%


Remaining = 40%


20% of 40% = 8%

[arunabha2003]

2. From the salary of an officer, 10% is deducted as house rent, 20% of the rest, he spens on conveyance, 20% of the rest he pays as income tax and 10% of the balance, hE spends on clothes. Then, he is left with Rs. 15,552. Find his total salary.


(a) Rs. 25,000


(b) Rs. 30,000


(c) Rs. 35,000


(d) Rs. 40,000





ANS: Salary* (90/100 * 80/100 * 80/100 * 90/100) = 15552


=> Salary * (51.84/100)= 15552


=> Salary = 15552 * 100/51.84 = 30,000

3. Aman gave 40% of the amount he had to Rohan. Rohan in turn gave one-fourth of what he received from Aman to Sahil. After paying Rs. 200 to the taxi driver out of the amount he got from Rohan, Sahil now has Rs. 600 left with him. How much amount did Arnan have?


(a) Rs. 4000


(b) Rs. 8000


(c) Rs. 12,000


(d) Data inadequate





ANS: Aman * 40/100 * 1/4 = 200+600 = 800


=> Aman = 8,000

4. Sameer spends 24% of his monthly income on food and 15% on the education of his children. Of the remaining salary, he spends 25% on entertainment and 20% on conveyance. He is now left with Rs. 10,736. What is the monthly salary of Sameer?


(a) Rs. 27,600


(b) Rs. 28,000


(c) Rs. 31,200


(d) Rs. 32,000





ANS: Sameer * (100 - 24 - 15)% * (100 - 25 - 20)% = 10,736


=> Sameer * 61/100 * 55/100 = 10,736


=> Sameer = 32,000

5. 405 sweets were distributed equally among children in such a way that the number of sweets received by each child is 20% of the total number of children. How many sweets did each child receive?[/b]
(a) 9
(b) 15
(c) 18
(d) 45

ANS: Let no of children be x
x/5 = 405/x
x*x = 405*5
x = sq rt of 2025 = 45

[chayanika]

1.a)8%


let the salary be x
then, expenditure on food and children's education=35x/100+25x/100


i.e. 60x/100


remaining portion of salary=x-60x/100 = 40x/100


hence, expenditure on house rent=80% of 40x/100=32x/100


hence total expenditure=60x/100+32x/100 = 92x/100


hence, the portion of salary the man is left with = x-92x/100


i.e. 8% of the income



2.b) Rs. 30000


90% of 80% of 80% of 90% of salary=15552
i.e. 51.84/100 of salary=15552
i.e. salary=30000


3.b)Rs. 8000


let Aman had Rs. x
then rohan had=40% of x
and sahil had=1/4*(40% of x) i.e. 1/4 * 40/100 * x=x/10
according to the question, x/10-200=600
hence x=8000


4.d) Rs. 32000


(100-(25+20))% of (100-(24+15))% of salary=10736
i.e. 55% of 61% of salary=10736
i.e. salary=32000


5.d)45
let the no of children be x
sweet received by each child=405/x
again according to question, 405/x=20% of x
i.e. 405/x=x/5
i.e. x*x=2025
hence x=45
