Correct Answer: 1250
Explanation:
Let initially 'X' ticket has been sold.
So now in 2nd week 20% increases, so
=> X x 120/100
In 3rd week 16% increases, so
=> X x (120/100) x (116/100)
In 4th week 20% decrease, so
=> X x (120/100) x (116/100) x (80/100) = 1392
X = 1250.
Correct Answer: 5/4
Explanation:
Literally any percentage means divide by 100.
So
. That can be reduced to 5/4.

Correct Answer: 12.5%
Explanation:
Let p% of a day is 3 hrs.
We know that a day has 24 hrs.
=> p x 24/100 = 3
=> p = 300/24
=> p = 12.5%
Hence, 3 hrs is 12.5% of a day.
Correct Answer: Rs. 5917
Explanation:
Let the Original capital amount be Rs. P
Given after 2 years the amount is Rs. 10000
Rate of interest = 30%
According to the question,
Therefore, the capital amount P = Rs. 5917
Correct Answer: 15,000
Explanation:
Ramesh : Rajesh =(50,000*36) : (75,000*30) =4 : 5.
Therefore, Rajesh's share=Rs.(27,000*5/9)= Rs.15,000.
Correct Answer: 70% is better
Explanation:
Let Price be Rs.100
1st CASE:
Then 100 x 70/100 = 70
=> price after discount = 100-70 = Rs.30
2nd CASE:
Then 100 x 40/100 = 40
=> price after discount = 100-40 = Rs.60
then
60 x 30/100 = 18
=> price after 2 consequent discount = 60-18 = Rs.42
=>from 1 and 2 cases, 70% discount is better.
Correct Answer: 120
Explanation:
K x 3/8 = 141 => K = 376
376 x 32.08/100 = 120
Correct Answer: 8 %
Explanation:
Let the price of 1 litre of diesel be Rs.x and let Karthik initially buy 'y' litres of diesel.
Therefore, he would have spent Rs. xy on diesel.
When the price of diesel increases by 25%, the new price per litre of diesel is 1.25x.
Karthik intends to increase the amount he spends on diesel by 15%.
i.e., he is willing to spend xy + 15% of xy = 1.15xy
Let the new quantity of diesel that he can get be 'q'.
Then, 1.25x x q = 1.15xy
Or q = (1.15/1.25)y = 0.92y.
As the new quantity that he can buy is 0.92y, he gets 0.08y lesser than what he used to get earlier.
Or a reduction of 8%.
Correct Answer: Rs. 3136
Explanation:
Let total amount = Rs. P
Total expenditure = (23 + 33 + 19 + 16)% of P = 91%ofP
Remaining money = (100 - 91)% of P = 9% of P
But given in the question that,
9% of P = 504
9p/100 = 504
=> P = 50400/9
=> P = Rs. 5600
Required money spent on Food & Insurance = 23 + 33 %
= 56% of 5600
= 56 x 5600/100 = 56 x 56 = Rs. 3136
Correct Answer: 25 kgs
Explanation:
Initial wheat per kg cost be Rs. 100
Then, monthly expenditure of the family = 30 x 100 = 3000
After increase in cost,
Let P be new monthly consumption of family.
P x 132 = 110/100 x 3000
=> P = 25 kg.
