Correct Answer: 149600 kgs
Explanation:
Let the total quantity of gold be p kgs.
According to the question,
50% of p + 25% of p + 12.5% of p = 130900
87.5% of p = 130900
p = 130900 x 100/87.5 = 149600 kgs.
Therefore, the initial gold quantity that king has = p = 149600 kgs.
Correct Answer: decrease 12%
Explanation:
Given the price of a commodity is decreased by p = 20%
And its consumption is increased by q = 10%
Now, required increase or decrease in the expenditure on the commodity can be
p + q + pq/100 = -20 + 10 - 200/100 = -10 - 2 = -12%.
Hence, decrease in the expenditure = 12%
Correct Answer: 606
Explanation:
56% of 870 = 56x870/100 = 487.20
82% of 180 = 82x180/100 = 147.60
32% of 90 = 32x90/100
487.20 + 147.6 - 28.8 = ?
? = 634.8 - 28.8
? = 606.

We have P = 8748, R = -10 and n = 3
Therefore, the purchase price of the machine
=
=
= 8748 x (100/90) x (100/90) x (100/90)
= 12,000.
Therefore, the purchase price of the machine was Rs. 12,000.
Correct Answer: 8000
Explanation:
Let the amount collected be 'A'
Then, from the given conditions,
A x 110/100 x 90/100 = 7920
A x 0.99 = 7920
A = 7920/0.99
=> 8000
Correct Answer: 2834
Explanation:
Let the total number of votes polled in the election be 100k.
Number of valid votes = 100k - 20% (100k) = 80k
Let the number of votes polled in favour of K and L be a and b respectively.
a - b = 15% (100k) => a = b + 15k
=> a + b = b + 15k + b
Now, 2b + 15k = 80k and hence b = 32.5k
It is given that 100k = 8720
32.5k = 32.5k/100k x 8720 = 2834
The number of valid votes polled in favour of L is 2834.
