__Detailed Solutions:__

1. cp= 100

sp = 120 (with tax)

new sp = 100-5=95

effective discount= 120-95=25

at sp 95 disc=25

at sp 3325, disc= 25/95 *3325=875

2. Total wages= no of workers*wage per worker

60xy= 3x * 20y

54xy=

2x * 27y

2x * 27y

Gain %= 60-54/60*100=

10%

10%

3. Suppose Ramu paid rs 100

Disc=25%=25= cost of sisterâ€™s wristband.

Cost of Ramuâ€™s wristband=75thus Ramuâ€™s wristband and

sisterâ€™s wristband cost are in ratio = 3:1

sisterâ€™s wristband cost are in ratio = 3:1

Sisterâ€™s wristband=

940 rs ( given ) hence ramuâ€™s wristband cost = 940*3=2820

940 rs ( given ) hence ramuâ€™s wristband cost = 940*3=2820

4. From I let cp = x

Mp = 13x/10

From iii, sp=90% mp

Thus from I and iii, we get,

sp = 90/100 * 13x/10=117x/100

sp = 90/100 * 13x/10=117x/100

Gain= 117x/100 -x=

17x/100

17x/100

Hence I and iii are sufficient

5. Total cost of 4 tv sets = 3+5=8 lakh.

Sp of 4 tv sets=8*1.5=12 lakh

Sp of 1 tv= 4 lakh

Sp of rest 3

tvs=12-4=8 lakh.

tvs=12-4=8 lakh.

Average sp of all 3 tvs=8/3=2.66 lakh

6. Let the labelled price be Rs.x. Then, 120% of x = 2880

Therefore x=(2880Ã—100/120) = 2400.

Therefore x=(2880Ã—100/120) = 2400.

C.P = 85% of Rs.2400

= Rs(85/100Ã—2400) =Rs.2040

= Rs(85/100Ã—2400) =Rs.2040

7. The merchant had

initially marked her goods up by 40%.

initially marked her goods up by 40%.

Let us assume that her cost price of the goods to be rs 100.

Therefore, a 50% mark up would have resulted in her marked

price being rs100 + 40% of rs100 = rs100 + rs40 = rs140.

price being rs100 + 40% of rs100 = rs100 + rs40 = rs140.

The question states that she finally sells the product at no

profit or loss. This essentially, means that she sells the product at cost

price, which in this case would be rs 100.

profit or loss. This essentially, means that she sells the product at cost

price, which in this case would be rs 100.

Therefore, she had

offered a discount of $40 on her marked price of $140. Hence, the % discount

offered by her = [40/140]*100 = 28.57%.

offered a discount of $40 on her marked price of $140. Hence, the % discount

offered by her = [40/140]*100 = 28.57%.

8. Calculate profit percent as Profit% = (profit/cost) * 100

9. Let original Cost price is x

Its Selling price =

105/100 * x = 21x/20

105/100 * x = 21x/20

New Cost price = 95/100 * x = 19x/20

New Selling price = 110/100 * 19x/20

= 209x/200 [(21x/20)

â€“ (209x/200)] = 1

â€“ (209x/200)] = 1

=> x = 200

10. Let the cost price of 1 brinjal be Rs 1.

Therefore, cost price of 20 brinjals = 20 * 1 = Rs 20

The selling price of 25 brinjal = cost price of 20 brinjal =

Rs 20.

Rs 20.

Now, we know the

selling price of 25 brinjal

selling price of 25 brinjal

Let us find the cost

price of 25 brinjal.

price of 25 brinjal.

Cost price of 25

brinjals= 25 * 1 = Rs 25.

brinjals= 25 * 1 = Rs 25.

Therefore, profit made on sale of 25 brinjals =

Selling price of 25 brinjals â€“ cost price of 25 brinjals =

20 â€“ 25 = â€“ Rs 5. As the profit is in the negative, the merchant has made a

loss of Rs 5.

20 â€“ 25 = â€“ Rs 5. As the profit is in the negative, the merchant has made a

loss of Rs 5.

Therefore, % loss =

(Loss/Cost Price) * 100

(Loss/Cost Price) * 100

% loss = [ -5/25 ]
*100 = 20%.
