Correct Answer: 40%
Explanation:
Let the original price of the cycle be 100. After the first reduction the price will be 75.
This new price is then reduced by 20% = 0.8 x 75 = 60
60 represents a reduction of 40 percent on the original.
Correct Answer: 36.975
Explanation:
30 + (.0825 x 30) + (15% x 30)
Now
=> 0.0825 x 30 = 2.475 -----(1)
=> 15% of 30 = 450/100 = 4.5 -----(2)
Hence, from (1) & (2)
30 + (.0825 x 30) + (15% x 30)
= 30 + 2.475 + 4.5
30 + (.0825 x 30) + (15% x 30) = 36.975.
Correct Answer: Rs. 20
Explanation:
Let the original price of rice be Rs. x
Let rice a man can buy for Rs. 500 at rs. x/kg be = R kgs
From given data, for Rs. 500
x ---- R kgs
(x + 25x/100) ---- (R - 5) kgs
=> Rx = (R - 5)(x + 25x/100)
=> Rx = (R - 5)(125x/100)
=> 100Rx = 125Rx - 625x
=> R = 25
So at rate of Rs. x/kg, man get 25 kgs for Rs. 500
=> x = 500/25 = Rs. 20
Correct Answer: 87%

Explanation:
Let the salary of Karthik 2 years ago be Rs.100
So, Lucky's salary 2 years ago was Rs.50
Karthik's present salary has seen two 10 percent increases. So as Lucky's salary.
So, Karthik's salary 1 year ago = 100 + 10% of 100 = 100 + 10 = 110.
Karthik's present salary = 110 + 10% of 110 = 110 + 11 = 121.
Lucky's salary 1 year ago = 50 + 10% of 50 = 50 + 5 = 55
Lucky's present salary = 55 + 10% of 55 = 55 + 5.5 = 60.5
Lucky's present salary of 60.5 = 50% of Karthik's present salary of 121.

Correct Answer: 62.5 %
Explanation:
Let total population = p
number of females = 5p/9
number of males =(p-5p/9) = 4p/9
married females = 30% of 5p/9 = 30x5p/100x9 = p/6
married males = p/6
unmarried males =(4p/9-p/6) = 5p/18
Percentage of unmarried males in the total males = {(5p/18)/4p/9}x100 = (5p/18)x(9/4p) = 125/2 % = 62.5%
