Find the missing number,
7, 8, 15, 34, 71, 132, ___________
Solution
1st order difference of the series is:
8-7 = 1
15 - 8 = 7
34 - 15 = 19
71 - 34 = 37
132 - 71 = 61.
2nd order difference is:
7-1 = 6
19 - 7 = 12
37 - 19 = 18
61 - 37 = 24
So, the next 2nd order difference should be the next multiple of 6 i.e. 30.
This means that the next 1st order difference = 61 + 30 = 91.
And the next term of the series = 132 + 91 = 223.
Arrange the following fractions (A-E) in their ascending order.
A.5/8
B.7/12
C.13/16
D.16/19
E.3/4
Choose the correct answer from the option given below:
Solution
To compare the fractions, we can make their denominators same.
LCM of 8, 12, 16, 19 and 4 is 16*19*3 = 912.
A = $$\frac{570}{912}$$
B = $$\frac{532}{912}$$
C = $$\frac{741}{912}$$
D = $$\frac{768}{912}$$
E = $$\frac{684}{912}$$.
These fractions can be arranged in ascending order as: B A E C D.
A mixture contains alcohol and water in the ratio 4 : 3. If 5 liters of water is added to the mixture, the ratio becomes 4 : 5. The quantity of alcohol in the given mixture (in liters) is :
Solution
Let us assume the quantity of alcohol and water in the mixture to be 4x and 3x respectively.
After adding 5 litres of water, the new quantity of water becomes 3x+5 litres.
New ratio of alcohol and water is 4:5
==> $$\frac{4x}{3x+5}=\frac{4}{5}$$
==> x = 2.5.
Volume of alcohol = 4x = 4*2.5 = 10 litres.
The value of $$\frac{3.157 \times 4126 \times 3.198}{63.972 \times 2835.121}$$ is approximately equal to:
If (x + y) : (x - y) = 11 : 1, then $$\frac{5x + 3y}{x - 2y}=$$
Solution
$$\frac{x+y}{x-y}=\frac{11}{1}$$
x+y = 11x-11y ==> 10x = 12y ==> 5x = 6y OR x = 6y/5.
We substitute this value in the given expression to get:
$$\frac{6y+3y}{\frac{6y}{5}-2y}=\frac{9y}{-\frac{4y}{5}}=-\frac{45}{4}$$.
If the difference between compound and simple interest on a certain sum of money for 3 years at 2% per annum is ₹604, then what is the sum ?
Solution
Share
Difference between $$CI$$ and $$SI$$ ($$D$$) = ₹604
Time ($$n$$) = 3 years
Rate of interest ($$r$$) = 2% per annum
$$SI = \dfrac{P \times r \times n}{100}$$
For $$n = 3$$ and $$r = 2$$:
$$SI = \dfrac{P \times 2 \times 3}{100} = \dfrac{6P}{100} = 0.06P$$
Now, $$CI = P \left[ \left(1 + \dfrac{r}{100}\right)^n - 1 \right]$$
For $$n = 3$$ and $$r = 2$$:
$$CI = P \left[ \left(1 + \dfrac{2}{100}\right)^3 - 1 \right]$$
$$CI = P \left[ (1.02)^3 - 1 \right]$$
$$CI = P [1.061208 - 1]$$
$$CI = 0.061208P$$
The difference $$D = CI - SI$$: $$604 = 0.061208P - 0.06P$$
$$604 = 0.001208P$$
$$P = 5,00,000$$
