Hence, 30% of Rs. 500 = Rs. 150.
Correct Answer: 12
Explanation:
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
But tins are available in only 4kgs
Then, no. of tins req = 47.7/4 = 11.4 => 12 tins
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.
Correct Answer: 1950.50
Explanation:
Correct Answer: 84%
Explanation:
Let the number be 'x'
Then, according to the given data,
=
= 84%
Correct Answer: 525
Explanation:
Given 40% minimum passing marks for boys = 483 + 117 = 600
=> 1% = 600/40
=> 100% = 600 x 100/40 = 1500
Minimum passing marks for girls = 35% of 1500 = 35 x 1500/100 = 525.
Correct Answer: 4:3
Explanation:
Let the numbers be p & q
q-p/4 = 4q/6
=> q-4q/6 = p/4
=> 2q/6 = p/4
=> p/q = 4/3
Correct Answer: 84.8
Explanation:
Let 'M' be the maximum marks in the examination.
Therefore, Madhu got 32% of M = 32M/100 = 0.32M
And Kumar got 42% of M = 42M/100 = 0.42M.
In terms of the maximum marks Kumar got 0.42M - 0.32M = 0.1M more than Madhu. ---- (1)
The problem however, states that Kumar got 16 marks more than the cut-off mark and Madhu got 8 marks less than the cut-off mark. Therefore, Kumar has got 16 + 8 = 24 marks more than Madhu. ---- (2)
Now, Equating (1) and (2), we get
0.1M = 24 => M = 24/0.1 = 240
'M' is the maximum mark and is equal to 240 marks.
We know that Madhu got 32% of the maximum marks.
Therefore, Madhu got 32 x 240/100 = 76.8 marks.
We also know that Madhu got 8 marks less than the cut-off marks.
Therefore, the cut-off marks will be 8 marks more than what Madhu got
= 76.8 + 8 = 84.8.
