Profit & Loss General Questions

(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)

C.P. of 12 balls = S.P. of 17 balls = ₹ 720.

C.P. of 1 ball = ₹		720		= ₹ 60.
		12

85 : 18700 = 115 : x

x =		18700 x 115		= 25300.
		85

Hence, S.P. = ₹ 25,300.

Let C.P. of clock be ₹ x.

Then, C.P. of 90 clocks = ₹ 90x.

⇒ [(110% of 40x) + (120% of 50x)] - (115% of 90x) = 40

⇒ 44x + 60x - 103.5x = 40

∴ 0.5x = 40 => x = 80

Marked price = ₹ 300

C.P. = 100/120 x 300 = ₹ 250

Sale price = 90% of ₹ 300 = ₹ 270

∴ Required gain % = 20/250 x 100 = 8%.

Let C.P. of each horse be ₹ x and C.P. of each cow be ₹ y.

Then, 4x + 9y = 13400 --------- (i)

And, 10% of 4x + 20% of 9y = 1880

⇒ 2/5 x + 9/5 y = 1880 => 2x + 9y = 9400 ----- (ii)

Solving (i) and (ii), we get : x = 2000 and y = 600.

∴ Cost price of each horse = ₹ 2000.

Let C.P. of the article be ₹ x.

Then, required ratio = 104% of x / 106% of x

= 104/106 = 52/53 = 52:53

Actual price = 95% of 90% of 85% of ₹ 12000

= (95/100 x 90/100 x 85/100 x 12000) = ₹ 8721.

Let the cost price for the manufacturer be ₹ X.

Then, 125% of 120% of 118% of X = 30.09.

⇒ (125/100 x 120/100 x 118/100 x X) = 3009/100

∴ 177/100 X = 3009/100 => X = ₹ 17

Clearly, the retailer gets 1 dozen out of 6 dozens free.

∴ Equivalent discount = 1/6 x 100 = 16 ²/₃%.

Let S.P. of 12 toffees be ₹ X.

Then,

⇒ 80 : 1 = 120 : X or X = 120/180 = 3/2

For ₹ 3/2, toffees sold = 12.

For Re. 1, toffees sold = 12 x 2/3 = 8
