Answers & Solutions:
1) Answer (C)
Let the total money be x.
Shares of 44 sons = x/10, 2x/10, 3x/10, 4x/10
Percentage = 3x/10x * 100 = 30%
2) Answer (B)
Budget = price*quantity
So we can see that price and quantity are inversely related.
Price has become 6/5, so if want to maintain the same budget the quantity consumed should become 5/6 of earlier quantity.
So percentage reduction = 1-5/6 = 1*100/6 = 16.67%
3) Answer (C)
Percentage of hemoglobin at the end of first month = 1.12*11.3 = 12.66%
At the end of second month = 0.76*1.12*11.3 = 9.62%
At the end of fourth month = 0.52*1.36*0.76*1.12*11.3 = 6.8%
So the correct option to choose is C – 6.8%.
4) Answer (A)
The required percentage = $\frac{52}{65}$ * 100 = 80%
5) Answer (D)
Number of numbers from 1-40 which have digit 2 in them = 13 (2, 12, 20, 21, …29, 32)
Percentage = (13/40)*100 = 32.5%
So the correct option to choose is D.
6) Answer (D)
Sum of first 10 even numbers = 2+4+6+8….20 = 2(1+2+3+…10) = 2*55 = 110.
Sum of first 30 natural numbers = 30*31/2 = 465
Percentage = (110/465)*100 = 23.66%
7) Answer (D)
Based on the given information, the following equation could be derived.
12x/5 = 3y/8 ==> y = 32x/5
==> x is the smallest among the two.
Percentage of x to y = $\frac{x}{32x/5}*100$ = (5/32)*100 = 15.6%
8) Answer (D)
Let C = x
B = 1.7x
A = 1.5*1.7x = 2.55x
==> A is 155% greater than C.
9) Answer (A)
Let the price per kg of rice be ‘p’ and the consumption (in kgs) per month be ‘c’.
So, money spent on rice in a month is ‘pc’
Now, the price increases by 25% which means the price becomes 1.25p
Let the new consumption be x.
=> 1.25px=pc or x=c/1.25
So, percentage decrease is $100-\frac{100}{1.25}=20$%.
Thus, A is the correct answer.
10) Answer (D)
A is the son of C. F is the daughter of A. So F is granddaughter of C.
11) Answer (A)
Let the price of chocolate be P and quantity that he buys be Q.
=> Increased price of chocolate = 1.3P
So, P X Q = 1.3P X Q’
=> Q’/Q = 1/1.3 $\approx$ 77%
=> Reduction in quantity will be 23%
12) Answer (D)
The percentage of land remaining after giving to the eldest son = 100% – 30% = 70%
Percent of land given to the second son = 30% of 70% = 21%
Thus, the land given to the third son = 100% – 30% – 21% = 49%
13) Answer (C)
Here the total subjects are 5 each subject has maximum 70 marks.
So total marks available are 70 × 5 = 350
Total marks of Koel is = 49 + 37 + 45 + 53 + 55 = 239
Percentage of Koel is = $\frac{239}{350}\times100$ = 68.28, which is equal to approximate 68 percent
14) Answer (A)
Passing percentage=663/1020*100=65%
Shreya percentage=612/1020*100=60%
Therefore she failed by 5%
15) Answer (D)
Let the Total marks is ‘T’ .
The unreserved guy got 300 but failed by 24 marks i.e. his pass mark is 300 + 24 = 324 .
Given that , the pass mark for unreserved guy is 54% of the total . i.e. $\frac{54}{100}$T = 324.
We get , T = 600 .
Also given that the pass mark for reserved guy is 40% of the total .i.e. {40/100}* 600 = 240.
16) Answer (A)
So Sohail’s overall percentage marks-
=$\frac{33+37+28+26+32}{300}$ $\times$100
=$\frac{156}{300}$ $\times$100
=52
17) Answer (E)
Prathik’s monthly salary = Rs. 10,000
Expenditure = 50% = Rs. 5000
Savings = Rs. 5000
New salary = 2* 10,000 = Rs. 20,000
New expenditure = 3*5000 = Rs. 15,000
Savings = 20,000 – 5,000 = Rs. 5,000.
% of salary Prathik manages to save = 5000/20,000 = 25%.
18) Answer (B)
REASONING
19) Answer (B)
Let maximum marks in the examination = $100x$
Minimum passing marks = $\frac{64}{100} \times 100x = 64x$
Marks scored by Sujata = $2240$
Acc to ques,
=> $64x + 128 = 2240$
=> $64x = 2240 – 128 = 2112$
=> $x = \frac{2112}{64} = 33$
=> Maximum marks = $100 \times 33 = 3300$
Marks scored by Meena = $2240 – 907 = 1333$
$\therefore$ % marks obtained by Meena = $\frac{1333}{3300} \times 100$
= $40.39 \% \approx 40 \%$
20) Answer (A)
Revenue = consumption $\times$ tax amount
Let consumption = 10 and tax = 10
=> Revenue = $10 \times 10 = 100$
Now, after tax is reduced by 10 %, new tax = $10 – \frac{10}{100} \times 10$
= $10 – 1 = 9$
Total revenue remains unchanged
=> New consumption = $\frac{100}{9}$
$\therefore$ % increase in consumption = $\frac{\frac{100}{9} – 10}{10} \times 100$
= $\frac{10}{9} \times 10 = \frac{100}{9}$
= $11\frac{1}{9} \%$
