Given 45 kg for painting
And 6% 0f 45 for wasting => 6x45/100 = 2.7 kg
Now total paint required = 45+2.7 = 47.7 kgs

Correct Answer: 14.285 %
Explanation:
Total Items = 7
Discounted = 1
Percentage = 1/7 x 100
= 14.285%
Correct Answer: 180
Explanation:
Given total number of cows = k
Now, 1st son share = k/2
2nd son share = k/4
3rd son share = k/5
4th son share = 9
(k) + (k/4) + (k/5) + 9 = k
=> k - (19k/20) = 9
=> (20k-19k)/20 = 9
=> k = 180.
Correct Answer: 400
Explanation:
1st day the girl read = 40%
2nd day she read = 34 %
Remaining percentage of book = 100% - (40% +34%) = 26%
But given last two days she read equal number of pages
=> Each day she read 26%/2 = 13%
Last day she read 52 pages = 13%
13% = 52
1% = 4
=> 100% = 400
Total pages in the book is 400.
