A. 7.1
B. 7.2
C. 7.3
D. 7.4

View Answer	Favorite Question	Report

Answer: Option C

Explanation:

প্রথম 20 ওভারে কৃত মোট রান = ( 20 × 3.5) = 70

অবশিষ্ট রান = 289 - 70 = 219 রান

সুতরাং, অবশিষ্ট 30 ওভারে গড়ে প্রতি ওভারে করতে হবে = 219/30 বা 7.3 রান

2574 . In three more years, Sabrina's grandfather will be six times as old as Sabrina was last year. When Sabrina's present age is added to her grandfather's present age, the total is 68. How old is Sabrina now?

A. 10
B. 11
C. 12
D. 13
E. None of these

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Let's denote Sabrina's current age as "S" years and her grandfather's current age as "G" years.

From the given information:

In three more years, Sabrina's grandfather will be six times as old as Sabrina was last year. This can be expressed as: (G + 3) = 6(S - 1)

When Sabrina's present age is added to her grandfather's present age, the total is 68. This can be expressed as: S + G = 68

Now, we have a system of two equations with two variables:

Equation 1: G + 3 = 6(S - 1) Equation 2: S + G = 68

Let's solve this system of equations using substitution. First, solve Equation 1 for G:

G = 6(S - 1) - 3

Now, substitute this expression for G into Equation 2:

S + (6(S - 1) - 3) = 68

Now, simplify and solve for S:

S + 6S - 6 - 3 = 68

7S - 9 = 68

7S = 68 + 9 7S = 77

S = 77 / 7 S = 11

So, Sabrina is currently 11 years old.

Answer: Option B

Explanation:

Given:

In △PQR, OR = 2 × PQ -2

And PR = PQ + 10

Formula Used:

The perimeter of a triangle is the sum of all sides of the triangle

Calculation:

Let the side PQ be x cm

So,

বা, QR = 2 × PQ -2

বা, QR = 2x -2 cm

And PR is

বা, PR = PQ + 10

বা, PR = x + 10 cm

The perimetre of the △PQR is

বা, 2x - 2 + x + x + 10 = 40

বা, 4x = 32 - 8

বা, x = 32 - 8

বা, x = 8 cm

বা, PQ = 8 cm

বা, QR = 2 × 8 -2 = 14 cm

বা, PR = 8 +10 = 18 cm

Answer: Option C

Explanation:

Let the amount of pulse of price Tk. 15 = x
and the amount of pulse of price Tk. 20 = y
Then the total amount of mixture = ( x + y) kg
total cost of mixture = 15x + 20y
but the price per kg of the mixture = Tk. 16.50
so, total price of (x + y) kg = 16.50(x + y)
According to question;
16.50(x + y) = 15x + 20 y
or, 16.50x + 16.50y = 15x + 20y
or, 1.50x = 3.50y
or, x/y = 3.50/1.50 = 0.7/0.3 = 7/3
so, the required ratio is 7 : 3

A. 3:2
B. 3:4
C. 3:5
D. 4:5

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Hints : Let he mixes the tea in ratio x:y

Therefore the cist price = 60x + 65y

selling price = 68.20(x + y)

we know,

profit = sells price - cost price

10% of (60x + 65y) = 68.20(x + y) - (60x + 65y)

10(60x + 65y) / 100 = 68.20x + 68.20y - 60x - 65y

6x + 6.5y = 820x + 3.20 y

2.2x = 3.3 y

x/y = 3/2

x:y = 3:2
