Amal purchases some pens at ₹ 8 each. To sell these, he hires an employee at a fixed wage. He sells 100 of these pens at ₹ 12 each. If the remaining pens are sold at ₹ 11 each, then he makes a net profit of ₹ 300, while he makes a net loss of ₹ 300 if the remaining pens are sold at ₹ 9 each. The wage of the employee, in INR, is

Answer :-
Let’s consider the total number of pens to be
(100 +x)
Let's consider the fixed-wage of the labour to be ‘w’
case (i): the net profit is 300
CP = 8(100 +x) + w
SP = 12 x 100 + 11 x = 1200 + 11x
Profit = SP - CP
300 = 1200 + 11x - 8(100 +x) - w
w - 3x = 100 → eq(1)
Case (ii): the net loss is 300
CP = 8(100 +x) + w
SP = 12 x 100 + 9 x = 1200 + 9x
Loss = CP - SP
300 = 8(100 +x) + w - 1200 - 9x
w - x = 700 → eq(2)
By solving equation (1) & (2) we get w = 1000.
Therefore, the wage of the employee is 1000.
Alternate solution:
We can also do this with a little intuition. The Rs 2 decrease per pen results in 300 loss from the case of 300 profit.
The net value of 600 resulted by selling the remaining pens at Rs 2 lesser.
If the number of remaining pens is x, then 2x = 600
So, x = 300.
Total pens = 100 + 300 = 400.
We can get the wage of an employee(w) by considering profit/loss
Profit = 300
100(12) + 300(11) - 400(8) -w = 300
w = 1000

If we rolled a dice 3 times. In how many ways we can get a sum of 8?
Sachin Yadav 04/01/2024 4:38 pm
(6,1,1) = 3 ways
(5,2,1) = 6 ways
(4,2,2) = 3 ways
(4,3,1) = 6 ways
(3,3,2) = 3 ways
The total no. of ways = 21 ways

In how many ways we can pick 4 numbers from first 20 natural numbers such that there is at least a gap of one number between any two picked numbers?
Neraj (TG) 05/01/2024 12:36 pm
ANSWER 2
Numbers before we pick first number = A
Numbers between first and second number = B
Numbers between second and third number = C
Numbers after we pick fourth number = D
ATQ,
A+B+C+D=16 [A≥0, B≥1, C≥1, D≥0]
A+B+C+D=14 [A≥0, B≥0, C≥0, D≥0]
NO OF WAYS= 14C2 = 91 WAYS

Q1. A person spent Rs 50000 to purchase a desktop computer and a laptop computer. He sold the desktop at 20% profit and the laptop at 10% loss. If overall he made a 2% profit then the purchase price, in rupees, of the desktop is?

Shivangi Garg 19/01/2024 1:40 pm
Sir,
D = Price of Desktop and L = Price of Laptop
0.2 D – 0.1 L = 2 % of 50000
0.2 D – 0.1 L = 1000
2D – L = 10000
D + L = 50000
Solving D = 20000

Selling price = 1.2 x 12000 = 14400
Cost price = 1.1 x 12000 = 13200
Profit = 14400 - 13200 =1200
Profit % = (1200/13200) x 100 =300/33 =100/11 = 9 1/11 %
Answer is b

A dishonest dealer claims to sell a product at its cost price . He uses a counterfeit weight which is 20% less than the real weight . Further he added 20% impurities to the product . Find the net profit percentage of the dealer !
TG Team 26/07/2018 7:23 pm
Hello Tarishi ,
Assume 100g costs 100 and adds 20% impurity
100g will become 120g
now instead of using 100 gm weigh he is using 80 gm weight
so 100g weight using counterfeit weight becomes (120/ 80 ) x 100 = 150 .
Hence profit percentage => 50%

Dev bought 100 kg rice for RS 1100 and sold it at a loss of as much money as he received for 20kg of rice. At what price did he sell the rice?
TG Team 01/08/2018 11:32 am
Hello Richa
We know ,
Selling Price = Cost Price - Loss
Hence , SP of 100 kg = CP of 100 kg - SP of 20 kg
SP of 120 kg = CP of 100 kg
SP : CP = 10 : 12
Hence SP of 100 kg rice = 10 x 1100/12
or Rs 55/6 per kg

let diameter of can be 10 and h be 1
earlier
v= 10*10*1= 100kg
now,
v=9*9*1 =81 kg
now let 1 kg = 1 rs.
earlier we were selling 100kg for 100rs
now we will sell 81 kg for 100 rs
means c.p =81
s.p =100
profit % =(19/81)*100 =23.47 (aprox)
earlier we were having zero profit now 23.47 so change =23.47
TG Team 11/08/2018 3:31 pm
The previous profit percentage is not known, so we cannot calculate the increase in profit percentage.
Hence , Option D

A dishonest shopkeeper cheats at the time of purchasing by 20% and at the time of selling by 35% using wrong weights and sells at the cost price.find his profit %
TG Team 24/09/2018 4:36 pm
Make a cheating of 20% while buying item means while buying he brought item worth Rs 120 in Rs. 100
Now at the time of selling he cheats 35% . So he sells item worth Rs 120 in price of 120 x (100/65) =Rs 184.6
hence profit percentage becomes : 84.6% .

One year payment to a servant is rs. 200 and one shirt. The servant leaves after 9 months and recieves Rs. 120 and a shirt. find the price of the shirt.
a. 80
b. 100
c. 120
d. Can't be determined
TG Team 03/10/2018 12:30 am
Let the price of the shirt be x .
Total yearly income = 200 + x.
Monthly = (200 + x)/12
9 months income = [(200 + x)/12] × 9
Now ,
120 + x = [(200 + x)/12] × 9
x = 120 .
TG Team 03/10/2018 12:37 am
Alternate Approach :
Loss of ₹80 in 3 months so in 12 months => ₹320
Contract is 200 + shirt.
So Shirt = 320 - 200 = ₹120
