Answer: Option A

Explanation:

Let the distance and time be d mile and T hours respectively.

So, d = 4T.

Again, d = (4 + 1) (T - 1/2)

or, 4T = 5(T - 1/2)

or, 4T = 5T - 5/2

or, 5T - 4T = 5/2

or, T = 5/2 hours

So, d = 4T = 4 x 5/2 = 10 mile.

Answer: Option B

Explanation:

১ দিনে টাইপ করে করার কথা ৮০ পেইজ। কিন্তু টাইপ করতে পারে ৬০ পেইজ। ১ দিনে টাইপ করতে পারে না ৮০ - ৬০ = ২০ পেইজ।
১০ দিনে টাইপ করার কথা = ৮০ × ১০ = ৮০০ পেইজ
অবশিষ্ট = ২০০০ - ৮০০ = ১২০০ পেইজ
২০ পেইজ জমে = ১ দিনে
১২০০ পেইজ জমে = ১২০০/২০ = ৬০ দিনে |

Answer: Option A

Explanation:

Let's use algebra to solve this problem. Let K represent Koushik's current age, and T represent Tahmid's current age. We'll set up equations based on the given information.

"Tahmid is four times as old as Koushik": T = 4K

"In x years, Tahmid will be three times as old as Koushik": In x years, Tahmid's age will be T + x, and Koushik's age will be K + x. So, we can write: T + x = 3(K + x)

Now, we have a system of two equations:

T = 4K
T + x = 3(K + x)
We can solve this system of equations to find Koushik's age (K) in terms of x.

First, substitute the value of T from the first equation into the second equation:

4K + x = 3(K + x)

Now, let's solve for K:

4K + x = 3K + 3x

Subtract 3K and x from both sides:

4K - 3K = 3x - x

K = 2x

So, Koushik's current age, in terms of x, is 2x.

B : C = 3 : 4 = 3× 2 : 4 × 2 = 6 : 8

A : B : C = 3 :6 : 8

A'S amount = ( 3× 1105) /( 3 + 6 + 8) = 195 Tk.

Answer: Option B

Explanation:

Tanveer earned Tk. 5.00 for every hour he worked, so his total earnings for last week can be expressed as 5x Tk.

He purchased y kg of rice at Tk. 12.00 per kg, so the total cost of rice he purchased can be expressed as 12y Tk.

His savings can be calculated by subtracting his total expenses from his total earnings, which gives:

Savings = (Total earnings) - (Total expenses) = 5x - 12y Tk

Therefore, the expression that shows Tanveer's savings is 5x - 12y Tk.
