10. Lucky saves 10% of his income while spends the rest of his income on food, clothes and rent in the ratio of 2 : 4 : 5. If the amount spent on clothes is Rs.2880, then find his income.
A) Rs.8100
B) Rs.7800
C) Rs.7920
D) Rs.8800
E) Rs.8740
Solutions:
1. D) Let CP = Rs.100 then MP = Rs.150
According to the question,
SP = 75 + 25 × 75/100 + 50 × 80/100 = 75 + 18.75 + 40 = Rs.133.75
Therefore profit% = (133.75 – 100)/100 × 100% = 33.75%
2. C) Let the age of Sunil and Karim is 7x and x respectively.
According to the question,
(7x – 4)/(x – 4) = 19/1 => 7x – 4 = 19x – 76 => 12x = 72 => x = 6
So the present age of Sunil = 42 years
After 4 years age of Sunil = 46 years
3. C) SI = PTR/100
=> 170400 = [(P × 10 × 5) + (P × 8 × 7) + (P × 12 × 3)]/100
=> 170400 = [50P + 56P + 36P]/100 => 170400 = 142P/100
=> P = Rs.120000
4. E) Let the quantity of the chemical in the bottle originally be x liters.
Then, quantity of chemical left in bottle after 5 operation
=> [x (1 – 12/x)5]/x = 32/243
=> (1 – 12/x)5  = (2/3)5
=> (x – 12)/x = 2/3
=> 3x – 36 = 2x => x = 36 litres
5. A) Let investment time of Gaurav was for x months
Ratio of their investment = Ratio of profit distribution
5 × 8 : 6 × x = 5 : 9
Therefore x = (40 × 9)/(6 × 5) = 12 months
6. A) Let the no. of males and females are 700 and 900.
No. of literate males = 700/14 × 11 = 550 and no. of illiterate males = 150
No. of candidates filled the form for SSC = 550/11 × 9 = 450
and no of candidates who absent in the exam day = 450/9 × 2 = 100
Therefore, Required ratio = 900 : 100 = 9 : 1
7. B) Bipin completes 50% of a task in 25 days.
In 1 day, Bipin completes 2% of the task.
Now, Madan is 40% as efficient as Bipin.
Therefore, In 1 day, % of work completed by Madan = 40% of 2 = 0.8%
Also, Suresh is 50% as efficient as Madan
In 1 day, % of completed by Suresh = 50% of 0.8 = 0.4%
In 1 day, working together Bipin, Madan and Suresh finish % of work = (2 + 0.8 + 0.4) = 3.2%
% of work to be completed = 50%
Therefore, Number of days which they will take = 50/3.2 = 125/8 = 15 5/8
8. D) It can be seen that by travelling 12 km (30 – 18) more at original speed, the bus reaches 9 minutes earlier. So, in order to reach 45 minutes earlier, it has to travel a distance of 60 km more at original speed.
So the distance between points Delhi and Jaipur = (18 + 60) = 78 kms.
9. B) In 1 hour, both pipes P and q and fill = 1/12 + 1/15 = 3/20
Again in 1 hour, both pipes P and R = 1/12 + 1/20 = 2/15
In 2 hours, part filled = 3/20 + 2/15 = 17/60
In 6 hours, part filled = (3 × 17)/60 = 17/20
Therefore remaining part = 1 – 17/20 = 3/20
As the pipes are opened alternatively, after P and R , now it is the turn for pipes P and Q.
Pipes P and Q can fill 3/20 part in 1 hour
Therefore total time taken = 6 + 1 = 7 hours
10. D) Lucky saves 10% of his income while spends the rest of his income on food, clothes and rent in the ratio of 2 : 4 : 5.
Let the amount spent on food, clothes and rent be 2x, 4x and 5x respectively.
Given, amount spent on clothes is Rs.2880.
Therefore, 4x = 2880 => x = 720
Total amount being spent on food, clothes and rent = 2x + 4x + 5x = 11x = 11 × 720 = Rs.7920
Now, the amount being spent is 90% of his income as he saves 10%.
90% of income = Rs.7920
Therefore, Income = 7920/90 × 100 = Rs.8800
