2911 . Sum of 4 consecutive even number is greater than three consecutive odd numbers by 81.If the sum of the least odd and even numbers is 59 then find the sum of largest odd and even numbers

A. 69
B. 53
C. 65
D. 72

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let 4 consecutive even numbers be x, x + 2, X + 4 and x + 6 respectively.
3 consecutive odd numbers be y, y + 2 and y + 4
According to question,
[x + x + 2 + x + 4 + x + 6]−[y + y + 2 + y + 4] = 81
= > (4x + 12)−(3y + 6) = 81
4x−3y = 81−12 + 6
4x−3y = 75
x + 4 = 59
On solving equations (i) and (ii), we get
X = 36
y = 23
The sum of largest odd and even number = x + 6 + y + 4 = x + y + 10 = 36 + 23 + 10 = 69

2917 . Sumi walks to her office at the rate of 4 miles per hour. If she increases her walking speed by one mile per hour, she would reach her office half an hour earlier than the previous time. What is the distance in miles of her office from her house?

A. 10
B. 12
C. 16
D. 20

View Answer	Favorite Question	Report

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.

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 |

B. 3x
C. 4x
D. 12x

View Answer	Favorite Question	Report

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.
