Total employees = 4800
45% of employees are males = $\frac{45}{100}$ x 4800 = 2160
60% of 2160 are equal to or older than 25
So 40% of 2160 are younger than 25 years = $\frac{40}{100}$ x 2160 = 864

If the numerator (assume to be x) is increased by 100%, it becomes 2x

and the denominator(assume to be y) is increased by 200%, it becomes 3y.

The new fraction is $\frac{4}{21}$ = $\frac{2x}{3y}$

Hence, simplifying we get fraction has $\frac{2}{7}$

Here, the salary is compounded every year.
Let salary be x.
22385=x(1+.1)2

x=18,500

Let x be monthly salary of Deepti Jain.
11%of x = 5,236.
x= 47600

Now total investment by Deepti Jain = Investment in Fixed Deposit + Investment in Mutual Funds + Investment in Insurance policies
= 19%+11%+7% = 37% of Salary = 37% of 47600
= 17,612

Total amount for 12 month = 12*17612 =2,11,344

Let Manas salary be x.
(2/3)rd of 12% of x = 2240
2/25 of x = 2240
x = 28000
Hence, Manas salary is 28000.

Let the number be x.
15% of x + 10% of x = 70
25% of x = 70
x = 70*4
x = 280
Now, twice of 280 = 280*2 = 560
The correct option is option C.

One eighth of the amount received by each son is equal to one tenth the amount received by each daughter.

As each daughter received Rs. 1.25 lakhs, it means that each son received 1.25*8/10 = 1 lakh.
So, the total amount received by 3 sons and 2 daughters is 3*1 + 2*1.25 = 5.5 lakhs

Hence, the amount received by the wife is 40%*5.5 = 2.2 lakhs

Amount received by each grandson is 1/10th the amount received by each daughter i.e 0.125 lakhs
Hence, the total amount received by 5 grandchildren is 5*0.125 = 0.625 lakhs

So, total received by wife and grandchildren is 2.2 + 0.625 = 2.825 lakhs = 2,82,500

Let the number be X.
So, 55%*X – 14%*X = 8610
Therefore, 41%*X = 8610
Or X = 8610 * 100/41 = 21000

Therefore, 85% of the number is 85%*21000 = 17,850

The marks the students gets is 520.
As the students failed by 5%, percentage of marks received by the student is 55-5 = 50%

Hence, the maximum aggregate marks that a student could have received is 520*100/50 = 1040

Let the two numbers be X and Y.
So, 80% of X = 3/5 of Y
or 4/5 * X = 3/5 * Y
Therefore, X:Y = 3:4

The quantity of salt in 3 litres of the solution is 10%*3 = 0.3 litres.
Let the quantity of water added be X.
So, (X+3)*5% = 0.3
Or, X+3 = 0.3*20 = 6
Hence, X=3 litres

The total percentage of his income that Mr. Davar spends equals 38% + 25% + 12% = 75%
Hence, the percentage of his monthly income that Mr. Davar saves is 100-75 = 25%
This equals Rs. 5,800

Hence,  Mr. Davar’s monthly income equals 5800 * 100/25 = Rs. 23,200

Let the five odd numbers be a, a+2, a+4, a+6 and a+8.
Hence, their sum equals 5a + 20 and their average is a+4

As given in the question, (a+4)/(a+8) = 84/100 = 21/25
Therefore, 25a + 100 = 21a + 168
Or, 4a = 68
Hence, a = 17

Hence, the first two numbers are 17 and 19 and their sum is 36

Let the money Gaurav inherited be equal to X

So, his hostel expenses equal 0.4X
Expenses on books and stationery is 0.2X
Remaining amount is X – 0.4X – 0.2X = 0.4X

Transport expenses is 50% of 0.4X = 0.2X
Remaining amount is 0.4X – 0.2X = 0.2X

He saves 50% of it, that is 0.1X and it equals 450.
So, the value of X is 450/0.1 = 4500
