Explanation:

ধরি, চেয়ারের ক্রয়মূল্য = x

টেবিলের ক্রয়মূল্য = x + 30% of x

প্রশ্নমতে, x + x + 30% of x = 690

2x + x × 30/100 = 690

200x + 30x = 69000

230x = 69000

x = 300

টেবিলের ক্রয়মূল্য = 300 + 30% of 300 = 300 + 90 = 390 টাকা

D. 350

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Given :

The diameter of the driving wheel = 140 cm

Speed of a bus = 66 km/hr

Concept Used:

Circumference of a circle = 2πr

Number of revolutions of a wheel (N) = D/d

d = Distance traveled by the wheel in 1 revolution

Calculation:

Distance travelled by bus in 1 hour = 66km = 6600 meter

Distance travelled by bus in 1 minute = (66000)/60 = 1100m

Distance travelled by a wheel in 1 revolution = Circumference = 2πr

Put 2r = 140 cm , 1 m = 100 cm , π =22/7

Therefore,

Distance traveled by a wheel in 1 revolution = (22/7) × (140/100)

Distance traveled by a wheel 1 revolution = 4.40 m

Now, using the above formula

N × 4.4 = 100

N = 250

∴ The number of revolutions per minute is 250.
