3873 . With 12.50% simple interest rate how many years are needed for a principal to get double ?

A. 8
B. 7
C. 6
D. 5

View Answer	Favorite Question

Answer: Option A

Explanation:

Principal with simple interest, A = P(1 + n r)

or, 2P = P(1 + n x 12.5/100)

or, 2P/P = 1 + n x 12.5/100

or, n x 12.5/100 = 2 - 1

or, n x 12.5/100 = 1

or, n = 1 x 100 / 12.5 = 8 years

Answer: Option D

Explanation:

Total marks in 6 test = (6*80) = 480

Total marks in 5 test = (70 + 65 + 90 + 75 + 85) = 385

So, marks in the 6th test = (480 - 385) = 95

Answer: Option A

Explanation:

To find the value of x when x is divided by y, the remainder is 5, and x/y = 5.20, you can use the following approach:

Let's first express the given information mathematically:

x divided by y with a remainder of 5 can be written as: x = 5y + 5

x/y = 5.20 can be written as: x/y = 520/100

Now, we have two equations:

x = 5y + 5 x/y = 520/100

We can solve the second equation for x:

x = (520/100) * y

Now, let's substitute this expression for x into the first equation:

5y + 5 = (520/100) * y

Now, solve for y:

5y + 5 = (5.20) * y

5y + 5 = 5.2y

Now, subtract 5y from both sides:

5 = 0.2y

Now, divide by 0.2:

y = 5 / 0.2

y = 25

Now that we have found the value of y, we can find the value of x using the first equation:

x = 5y + 5 x = 5 * 25 + 5 x = 125 + 5 x = 130

So, the value of x is 130.

Answer: Option B

Explanation:

X + Y + Z can do 1/6 of job in one hour……1
X + Y can do 1/8 of job in one hour……2
Y + Z can do 1/12 of job in one hour……3
adding 2&3 we get
X + Y + Y + Z = 1/8 + 1/12
X + Z + 2Y = 5/24…4
subtracting 1 from 4 we get
Y = 5/24 – 1/6 = 1/24.substituting the value of Y in 4 we have
X + Z + 2/24 = 5/24
X + Z = 5/24 – 2/24 = 3/24 = 1/8
hence X&Z will do 1/8 of job in one hour.
So X & Z will do the work in 8 hours.

A. 15 days
B. 20 days

D. 12 days

View Answer	Favorite Question

Answer: Option C

Explanation:

y can do in 1 day = 1/(7x5) = 1/35
x & y can do in 1 day = 1/20 + 1/35 = 11/140
Now,
11/140 work is done in 1 day
So, 1 work is done in 140/11 day
So, 11/14 work is done in (140x11)/(11x14) = 10 days.
