**R×100 / (mx+ny+pz)**

**[{2mn/(m+n)p} -1]× 100**

**Explanation:**

**1.** Part sold at 24% profit = 1-(1/3+1/4) = 5/12

Value of commodity = (80×100) / (1/3*15+1/4*20+5/12*24)= 400

**2.** Gain or loss = [2*5*4/4(5+4) – 1] × 100 % = 11.11%

Sign is + ive so gain 11.11%

**3.** 10 = x-5 – 5x/100

19x/20 = 15; x=15.789% = approx 15.8%

**4.** Let C.P. be Rs. x and S.P. be Rs. y.

Then, 3(y – x) = (2y – x) y = 2x.

Profit = Rs. (y – x) = Rs. (2x – x) = Rs. x.

So profit % =100%

**5.** Let CP is x.

Then (1920-x)/x*100= (x-1280)/x*100

On solving x=1600

Selling Price = 1600*125/100= Rs. 2000

**6.** Cost price of 1 Toy = 375/12= 31.25

Selling price of 1 toy = Rs.33

Profit= Rs (33-31.25) =1.75

Profit% = 1.75/31.25*100= 5.6

**7.** Lcm of 5&6 =30

Cost price of 30 articles= 5/6*30 = 25

Selling Price of 30 articles = 6/5*30 =36

% profit = (36-25)/25*100= 44%

**8.** Cost price of 17 toys – Selling price of 17 toys = cost Price of 5 toys

Cost price of 12 toys = selling Price of 17 toys= 720

Cost price of 1 toy= 720/12= 60

**9.** Both I & II are sufficient to find the exact amount of profit .

**10.** Selling Price With Profit of 10 % of total cost = 3000*10*110/100= 33000

Selling Price of 2 cows with 5% loss= 6000*95/100= 5700

Difference = 33000-5700= 27300;

So rate of the cows for selling to gain 10% profit on total = 27300/7= Rs. 3900

(because 1 cow died so remaining= 10-1-2=7)
