5-(-5) = 10
20-5= 15
Ratio of cost price of book1 and book2 = 3:2
Then cost price of book 1 is given by
(3/5) x 100 = Rs. 60.
Assume A be the cost price.
Therefore,
=> A = Rs 37,500.
SP = Rs.800 ; Profit = 25%
Now, CP = Rs.640
Loss = 25% = 25% of Rs.640 = Rs.160
Thus, SP = CP - Loss = Rs.640 - Rs.160 = Rs.480
The servant worked for 9 days instead of 12 days, he should receive 9/12 of his total payment
Let the price of 1 shirt be Rs. S
i.e., 3/4 (400 + S).
However, the question states that the servant receive Rs. 280 + S where S is the price of the shirt.
By equating the two equations we get 3/4 (400 + S) = 280 + S.
Therefore, Price of the shirt S = Rs. 80.
Let C.P.= Rs. 100.
Then, Profit = Rs. 320,
S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295
Required percentage = (295/420) * 100
= 70%(approx)
Cost of 4 mangoes = Rs. 6
Cost of 1 mango = Rs. 6/4 = Rs. 1.5
Now, Selling Price of 4 mangoes = Rs. 4
Selling Price of 1 mango = Rs. 4/4 = Rs. 1.0
Hence, the shopkeeper incurs a loss.
Required loss% = loss/C.P x 100
Loss = 1.5 - 1 = 0.5
C.P = 1.5
Loss% = (0.5/1.5) x 100
= (5/15) x 100
= 1/3 x 100
= 100/3
= 33.333%.
From the given data,
The cost price of the article = 5640 x 100/60 = Rs. 9400
The selling price of the article to gain 25% profit = 9400 x 125/100 = Rs. 11750.
Since S.P. = 5 (M.P. - S.P.) => 5 M.P. = 6 S.P.
M.P. = (6/5) S.P.
Since the percentage discount = Percentage profit,
Therefore, 1/6 = (S.P/C.P) ? 1 => S.P = (7/6) C.P
M.P = 6/5 S.P = 6/5 x 7/6 C.P = 7/5 C.P
Therefore, Ratio of discount to C.P
= (M.P ? S.P)/C.P = [{(7/5)C.P - (7/6)C.P} / C.P.]
= 7/30
Therefore, the ratio is 7 : 30
Income = Rs. 100
Expenditure = Rs. 80
Savings = Rs. 20
Present Expenditure 80x(15/100) = Rs. 12 = 80 + 12 = Rs. 92
Present Savings = 100 ? 92 = Rs. 8
100 ------ 8
? --------- 400 => 5000
His salary = Rs. 5000
Article I Article II
-20 25%
5%
20% 25%
4 : 5
Now, Selling of first article = (4-20%) = 0.8
Selling of second article = (5+25%) = 6.25
Therefore the ratio of selling price = 8 : 62.5
Cost price of the article is given by
= 400x100/(20+20)
= Rs.1000
