3619 . x, y are positive integers. When x is divided by y, the remainder is 5. If x/y=5.20, what is the value of x?

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.

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.

Answer: Option B

Explanation:

Let the number of pens be N.

Then, price of each pen = 120/N

He would get (N + 2) pens if the price of each pen was [120/N - 3].

So, 120 / (N + 2) = (120/N) - 3

or, 120 / (N + 2) = (120 - 3N) / N

or, 120N = (120 - 3N) (N + 2)

or, 120N = 120N + 120 x 2 - 3N2 - 3N x 2

or, 3N2 + 6N + 120N - 120N - 240 = 0

or, 3N2 + 6N - 240 = 0

or, N2 + 2N - 80 = 0

or, N2 + 10N - 8N - 80 = 0

or, N(N + 10) - 8(N + 10) = 0

or, (N + 10) (N - 8) = 0

or, N - 8 = 0 [N + 10 = / 0]

So, N = 8
