SOLUTIONS:

Explanation:
Total number of votes = 7500
Given that 20% of Percentage votes were invalid
1st candidate got 55% of the total valid votes.
Hence the 2nd candidate should have got 45% of the total valid votes
=> Valid votes that 2nd candidate got = total valid votes x (45/100)
7500*(80/100)*(45/100) = 2700

2.
Given, fresh fruit has 68% water.so remaining 32% is fruit content. weight of fresh fruits is 100kg
Dry fruit has 20% water.so remaining 80% is fruit content.let weight if dry fruit be y kg.
Fruit % in freshfruit = Fruit% in dryfruit
Therefore, (32/100) x 100 = (80/100 ) x y
we get, y = 40 kg.

3.

4.Explanation:
Let the total number of children be x.
Then, x * (20% of x) = 405
=> x * 20x/100 = 405
15x2 = 405
=> x=45
Number of sweets received by each child = 20% of 45 = 9.

Explanation:
Saving  = 50% of (100 - 40)% of (100 - 30)% of Rs. 18,400 = Rs. (50/100 * 60/100 * 70/100 * 18400) = Rs. 3864.

6.

7.Explanation:
Let there be x voters and k votes goes to loser then
0.8x - 120 = k + (k + 200)
k+200 = 0.41x
=> k = 1440
and  (k + 200) =1640
Therefore  1440/3200 x 100 = 45%

8.Explanation:
Actual price = Rs. (25 + 2.50) = Rs. 27.50.
Saving = 2.50
Percentage Saving = [(2.50/27.50)*100]
= 2500/275
= 9111%
≈9%
