Answer: Option D

Explanation:

Let the cost price of the article be Tk. x.

∴ 3362 − x = x − 2346

∴ x = C.P. =	3362 + 2346	= 2,854/ -
	2

∴ S.P. corresponding to a 20% profit = 1.2 × 2854 = Tk. 3,424.8/ -

Hence, option D is correct.

Or, 4x = 40

Or, x = 10

So small number is 4x = 4×10 = 40

Or, x

Answer: Option D

Explanation:

Let the speeds of the car, train and bus be 5x, 9x and 4x km/hr respectively.
Average speed = (5x + 9x + 4x)/3 = 18x /3 = 6x km/hr.
Also, 6x = 72 = > x = 12 km/hr
Therefore, the average speed of the car and train together is = ( 5x + 9x)/2 = 7x = 7 x 12 = 84 km/hr.

Answer: Option C

Explanation:

Equivalent Discount,
= (A + B) - AB/100
= (10 + 5) - (10 × 5)/100
= 14.5%

Let MP = X
Now,
X - 14.5% of X = 171(Selling Price)
0.855X = 171
X = 200
Hence, MP = Tk. 200
Going through options,
200(MP) = = 10%(disc.) ⇒ 180 = = 5%(disc.) ⇒ 171(CP)
