Explanation:

Hints: let the investment Take was x for 14 months, y for 8 months and z for 7 months

14x : 8y : 7z = 5: 7 : 8

so, 14x/8y = 5/7

y = 49x/20

and 14x/7z = 5/8

z = 16x / 5

x : y : z = x : 49x/20 : 16x /5 = 20 : 49 : 64

A. 10
B. 12
C. 14
D. 16
E. None

View Answer	Favorite Question

Answer: Option C

Explanation:

P, Q & R alltogether can fill 1/6 th of the tank in 1 hour

So, in 2 hours they fill = 2×1/6 = 1/3 of the tank

Remining part to be filled = 1 - 1/3 = 2/3 of the tank

P & Q together in 7 hours can fill 2/3 of the tank

So, P & Q together in hour can fill = 2/(3×7) = 2/21 of the tank

So, R alone can fill in 1 hour = 1/6 - 2/21 = (7 - 4)/42 = 1/14 of the tank

Therefore, R alone can fill the tank in 14 hours.

Answer: Option A

Explanation:

Let S represent the price of one shirt in Tk, and let T represent the price of one tie in Tk.

From the given information, we can create two equations:

"Three shirts and five ties cost Tk. 23": 3S + 5T = 23

"Five shirts and one tie cost Tk. 20": 5S + T = 20

Now, we can solve this system of equations using the method of substitution or elimination. Let's use the elimination method:

First, we'll multiply the second equation by 5 to make the coefficients of T in both equations equal:

5(5S + T) = 5(20) 25S + 5T = 100

Now, we have the system of equations:

3S + 5T = 23
25S + 5T = 100

We can subtract equation 1 from equation 2 to eliminate T:

(25S + 5T) - (3S + 5T) = 100 - 23

Simplify:

22S = 77

Now, divide both sides by 22 to find the price of one shirt (S):

S = 77 / 22 S = 3.50

So, the price of one shirt is Tk. 3.50.

Answer: Option A

Explanation:

Hints: Answer not given.

A + B s 1 hour work = ( 1/12 + 1/15) = 3/20

A + C s hours work = ( 1/12 + 1/20) = 2/15

Part filled in 2 hrs = ( 3/20 + 2/15) = 17/60

part filled 6 hrs = (3× 17/60) = 17/20

Remaining part = ( 1 - 17/20) = 3/20

Now, it is the turn of A and B and 3/20 part is filled by A and B in 1 hour

Total time taken to fill the tank = ( 6 + 1) = 7 hrs

3503 . Three times a number minus 7 is 32. What is the twice of the number?

A. 26
B. 13
C. 39
D. 16
E. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

Let the number be N.

According to the question,

3N - 7 = 32

or, 3N = 32 + 7 = 39

So, N = 39/3 = 13

Therefore, twice of N or 2N = 2 x 13 = 26.
