Tech Mahindra Profit and loss Quiz 2

let the price of 100cm cloth be Rs100 but now he get 120cm cloth for 100 rupees.
actual cost of 1cm =100/120
=5/6
now instead of selling 100cm by cheating he sells 80cm cloth for 100 rupees
now the profit is ......?
C.P of 80cm cloth is (5/6)x 80= Rs 66.66
S.P of 80cm cloth is at a discount of 20%is 100x0.8= Rs 80
now %profit = [(80-66.66)/66.66]x100
= 20.01%
so the profit is approximately 20%

lets say 100 cm cloth price = rs 100

on buying 120 cm cloth he has rs 20 profit

on selling 80 cm cloth instead of 100 cm he had rs 20 profit again

overall profit = 20 + 20 = rs 40

so on a 100 cm cloth he is having rs 40 profit but he is also giving 20 percent discount that means he is having rs 20 profit on a rs 100 cloth

so 20 % profit .

In such cases, always loss occurs. It can be calculated by this formula,
= (loss or gain percentage)²/100 = 4.
That is 4% of loss.
Graphic Change method
100==20%(loss) ==>120==20%(gain) ==>96.
% Loss = 4%.

5000 widgets = 100,000/20
so we divide by 20 to get cost of 5000 widgets
Raw Material Costs = 10000/20 = 500Rs
Direct Labour Costs = 50000/20 = 2500Rs
Total Sale Price = 5000Rs
Gross Price = 5000 - 2500 - 500 = 5000 - 3000 = 2000

Cp of first dal=30*36=1080
Cp of secomd kind dal=26*20=520
Total cp=1080+520=1600
Total amt of dal=30+26=56kg
Total sp of dal =30*56=1680
Profit =1680-1600 =80

Answer: 13,200

The ratio of their investment is :

Anirudh : Harish : Sahil = 5 : 6 : 4

Sum of the ratios :

5 + 6 + 4 = 15

Anirudh = 5/15 × 135000 = 45000

Harish = 6/15 × 135000 = 54000

Sahil = 4/15 × 135000 = 36000

Their ratio after investment.

Anirudh = 45000 × 8 = 360000

Harish = 54000 × 6 = 324000

Sahil = 36000 × 4 = 144000

The ratios of their profits :

Anirudh : Harish : Sahil

(360000 : 324000 : 144000) 12000

(30 : 27 : 12)3

10 : 9 : 12

Sum of the ratios is = 23
This is the ratio of their profits :

Sahil's profit is :

12/23 × 75900 = 13200

Actually for these kind of questions there is a formula  or you can say the equation that  is helpful for solving the questions .( the standard equation is following:
x= (y/(1+(r/100))) + (y/(1+(r/100))^2) + (y/(1+(r/100))^3).............upto N term
Here X is the amount you have to pay and N equal the number of installments.
Here X =2522 ( 4022 - 1500 = 2522)
Now by putting values in the formula we get
2522 =(y/(1+(5/100))) + (y/(1+(5/100))^2 + (y/(1+(5/100))^3)
By solving it we get Y which is the installment per month
y= 926.10.

30 kgs X 8.50 = 255
20 kgs X 9.00 = 180
Total cost is Rs. 435 for 50 kgs.
50 kgs ÷ 435 is Rs. 8.7/- per kg.
To get 20% net profit Prabodh need to sell it for
Rs. 8.7 X 120/100  i.e.  Rs. 10.44

Let the cost price be Rs. x
Original Selling Price = Rs. 2770
Original Profit = (2770 - x) Rs.
Profit % = (2770 - x)*100/CP
Now, new Selling Price = Rs. 3000
Original CP = Rs. x
New profit = (3000 - x) Rs.
New profit % = (3000 - x)*100/CP
(3000 - x)*100/CP - (2770 - x)*100/CP = 10
(300000 - 100x)/CP - (277000 + 100x)/CP = 10
23000/CP = 10
10CP = 23000
CP = 23000/10
CP = 2300
So, the original Cost price is Rs. 2300

For Rakesh,
CP = 10,000   Profit = 10%
SP = ((100+P%)/100) * CP
SP = ((100+10)/100) * 10000
SP = 11,000
For Mohan,
CP= 11,000  Loss = 10%
SP = ((100-10)/100) * 11000
SP = 9900
Therefore, totally Rakesh gains Rs.(11000-9900) i.e. Rs. 1100

List price (MP) = ₹ 300, d1 = 15, d2 = 10
SP = (1 - d1/100) (1- d2/100) × MP
SP = (1 - 15/100) (1 - 10/100) × 300
SP = (1 - 3/20) ( 1- 1/10) × 300
SP = (20 -3)/20 (10 - 1)/10 × 300
SP = 17/20 × 9/10 × 300
SP = (17 × 27) /2 = ₹ 229.50
Hence, the selling price will be = ₹ 229.50
