c) 124,225.50
d) 140,550.25
e) 150,515.50
Solutions:
1.
E) Required rise % = (110
– 89)/89 × 100 = 23.59% ≈ 24%
2.
A) Average population = (142 + 240 + 93 + 180 +
130 + 160)/6 = 945/6 = 157500
3.
C) Required % = 99 ×
100/1027 = 9.64% ≈ 10%
4.
B) Average population = (150 + 170 + 180 + 215 +
230 + 240)/6 = 1185000/6 = 197500
5.
D) For Karnataka% rise = (155 –
148)/148 × 100 = 4.73%
For Bihar% rise = (270 –
250)/250 × 100% = 8%
For Gujarat% rise = (105 –
99)/99 × 100% = 6.06%
For Nagaland% rise = (230 –
215)/215 × 100% = 6.98%
For Maharashtra% rise = (145 –
140)/140 × 100% = 3.57%
For Haryana% rise = (190 –
175)/175 × 100% = 8.57%
State for highest % rise = Haryana.
6. A)
Total no. of Nonfiction and GK books sold by
Store C
= 88500 × 20/100 × 15/30 = 8850 …. (i)
Total no. of Nonfiction and GK books sold by Store
E
= 88500 × 25/100 = 14750 …… (ii)
Total no. of Nonfiction and GK books sold by Store
C and Store E
= 8850 + 14750 = 23600
Number of Fiction and GK books sold by Store
A = 17700 × 15/20 = 13275
B = 26550 × 8/15 = 14160
D = 13275 × 9/15 = 7965
Therefore total = 13725 + 14160 + 7965 = 35400 …. (a)
Difference between the number of Fiction and GK
Books sold by Store A, B and D together and number of NonFiction and GK books sold
by stores C and E
= 35400 – 23600 = 11800 …… (b)
Therefore, required percentage = b/a × 100 =
11800/23600 × 100 = 50%
7. B)
Average number of Fiction and GK Books sold by
Store A, B and D together
= Total/3 = 35400/3 = 11800
Total number of books sold by Stores C, D and E =
10% + 15% + 25% of total sales
= 50% of 88500 = 44250
Required percentage = 11800/44250 × 100 = 26.67%
8. A)
Nonfiction sold by A = 5/20 × 20% of 88500 = (5
× 20 × 88500)/(20 × 100) = 4425
Similarly for B = 12390; C = 2360; D = 5310; E =
6556 (approx)
Therefore required answer is B, D and E i.e 3 stores
9. D)
Total business of C = Rs.120360
Total number of books sold by Store C = 10% of 88500
= 8850
Number of Fiction = 15/30 × 8850 = 4425
Total cost = 445 × Rs.15.50 = Rs.68587.50 …. (i)
Number of Nonfiction = 8/30 × 8850 = 2360
Total cost = Unknown ….. (ii)
Number of GK books = 7/30 × 8850 = 2065
Total cost = 2065 × Rs.12.50 = Rs.25812.50 …. (iii)
Total cost of nonfiction = Total business – (i) – (iii)
= Rs.120360 – Rs.68587.50 – Rs.25812.50 = Rs.25960
Price per copy = Total cost of nonfiction/Number of
nonfiction = 25960/2360 = Rs.11
10.
A) Price of Fiction and Nonfiction is increased
by 10%.
Now, Fiction will cost Rs.17.05, Nonfiction
Rs.12.1, and GK Rs.12.50 (Unchanged).
Total business of C will be equal to
(4425 × 17.05 + 2360 × 12.1 + 2065 × 12.5) = Rs.
129814.75.
