A. 5 : 7 : 8
B. 20 : 49 : 64
C. 38 : 28 : 21
D. 18 : 28 : 56

View Answer	Favorite Question

Answer: Option B

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.

3275 . Three shirts and Five ties cost Tk. 23. Five shirts and one tie cost Tk. 20. What is the price of one shirt?

A. Tk 3.50
B. Tk. 2.50
C. Tk. 6.00
D. Tk. 3.00

View Answer	Favorite Question

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

3277 . 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.
