Detailed Explanation:

1.We Know 8.33% = (1 /12), so, (1/12) MP = 220
MP = 220 × 12 = 2640 and S.P =2640 – 220 = Rs 2420

2.Let  M.P of each of the saree = Rs 100
A paid 100 × (90 / 100) × (60 / 100) = Rs 54
B paid 100 ×(80 / 100) × (70 / 100) = Rs 56
C paid 100 × (76 / 100) × (74 / 100) = Rs 56.2
C paid the most and hence got the least discount.

3.To find the mark up %, use [ a + b +(ab/100)]
Formula,
16 = a – 6 +[(a)(-6) /100]
22= [a – (6a / 100)] ➾ 22 = [94/100] a  and a=(2200 / 94) = 23.4 %
Let C. P = 100, MP = 123.4.
S.P =123.4 × (90 / 100) = 114.76
Profit % = 14. 76%

4.Let  CP/gm = Rs.1
Actual CP is for 900gm = Rs 900
CP for 1 kg = Rs 1000, above which he claims to be selling at a profit of x%.
SP for 1 kg = Rs 1000 +[x / 100 (1000)]= 1000 + 10x
Actual Profit % = [SP – Actual CP  / Actual CP ] × 100
30 =[ [(1000 + 10x) – 900] / 900 ] × 100
30 × 9 = 100 + 10x ➾x = 17%

5.16.67 % = (1 / 6) , 7.14 % = (1 / 14)
Let CP of A = 600, then he sold to B for Rs 700, B sold it to C for Rs 650, amount spent by C = [(5 / 100) × 650] = 32.5
CP for C = 650 + 32.5 = 682.5 and he sells to A at profit of 10%
i.e., SP =682.5 × (110 /100) = 750.75
loss incurred by A = 750.75 – 700 = Rs. 50.75

6.Let investment of A& B = 3x and 2x& their percentage return = 4y% and 3y% then
[(4y / 100) × 3x] – 300 = (3y /100) × 2x
(12 / 100) xy – 300 = (6 / 100)xy
(6 / 100)xy = 300. Their combined earnings is (18 / 100)xy which is equal toRs 900.

7.10% of MP = 8, MP of sweets packet = 80, and amount she paid = 80 – 8 = Rs.72.

8.Total C.P on 3 cars = 1,00,000 × 3 + 1,25,000 = 4,25,000.
Total profit = (40/100)×425000=170000
Total S.P = 595000 out of which one of the car is sold for RS.145000
S.P for remaining two = 4,50,000
Price per car = (4,50,000/ 2)= Rs 2,25,000

9.Actual CP  ￫ Let  C.P of trader be Rs 1 / gram, he pays Rs 1000 for 1200 gm, hence his actual C.P.= (10 / 12) per gm, for 900 gm = (10 / 12) × 900
Actual SP   ￫ [He is charging according to 1000 gm]
C.P of 1000gm = Rs 1000, MP = 16000
S.P = 1600 – 10% = 1440
Actual Profit % = {[1440 – (9000 / 12) ] / [9000 / 12]} × 100
= (8280 / 12) × (12 / 9000) × 100
=92%

10.Ratio is 1: 4
Pencil         Eraser
S.P. / Unit                            X                 a
C.P./  Unit                           Y                  b
When 20 pencils are sold ￫ 20 x – 20 y = 6 a
i.e., 20 (x – y) = 6a
When 20 erasers are sold ￫ 20 b – 20 a= 8x
i.e., 20 (b – a) =  8x
Also % Profit = (6a / 20y)× 100 and % loss = (8x / 20b) × 100
Now (6a / 20y) = 2 (8x/ 20b)à 3a / y = 8x / b ……(i)
Also y : b = 3 : 2à (y / b) = (3 /2) or 2y = 3b, Putting in (i)
We get, 3a / (3/2)b = 8x / bà 2a = 8x and (a / x)  = (8/ 2)
i.e.,  x : a = 1:4
