2582 . In triangle PQR length of the side QR is less than twice the length of the side PQ by 2 cm. Length of the side PR exceeds the length of the side PQ by 10 cm. The perimeter is 40 cm. the length of the smallest side of the triangle PQR is:

A. 6 cm
B. 8 cm
C. 9 cm
D. 10 cm

View Answer	Favorite Question	Report

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

2584 . In what ratio must a grocer mix two varieties of tea worth TK. 60 a kg and TK. 65 a kg so that by selling the mixture at TK. 68.20 a kg he may gain 10% ?

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

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let the original price be P.

Now, the new price after increasing the original price by 15% = 1.15P

The final price after increasing the new price by another 15% = 1.15x1.15P = 1.3225P.

So, actual increament in the original price = {1.322P - P) / P} x 100 = 32.25%

[Shortcut: + 15 + 15 + (15x15)/100 = 32.25%]
