If the price of diesel increases by 25% and Karthik intends to spend only an additional 15% on diesel, by how much % will he reduce the quantity of diesel purchased ?
Options- A. 6.67 %
- B. 8 %
- C. 7.41 %
- D. 9 %
- Correct Answer
- 8 %
ExplanationLet 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 = 1.15xyLet 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: 120
Explanation:
K x 3/8 = 141 => K = 376
376 x 32.08/100 = 120
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: 432
Explanation:
There are 600 Kabaddi players
4% wear knee band on one leg
Remaining players = 600 x 0.96 = 576
Of the remaining, 25% wear knee bands on both leg
and Of the remaining, 75% do not wear knee bands .
So players not wearing knee bands = 0.75 x 576 = 576 x 3/4 = 144 x 3 = 432.
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: 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.
Correct Answer: 20%
Explanation:
Percentage of students passed in English = 60%
Percentage of students passed in Hindi = 45%
Percentage of students passed in both subjects = 25%
ATQ,
Percentage of students passed in only English = 60 - 25 = 35%
Percentage of students passed in only Hindi = 45 - 25 = 20%
Therefore, Percentage of students failed = 100 - (35 + 25 + 20)
= 100 - 80 = 20%.
Correct Answer: 1060
Explanation:
Given total number of students = 80
Total teachers = 5
Number of coupons each student got = 15 x 80/100 = 12
Number of coupons each teacher got = 25 x 80/100 = 20
Therefore, total number of shopping coupons = 80 x 12 + 5 x 20 = 960 + 100 = 1060.
Correct Answer: 24%
Explanation:
Let the cost price of each mango be Rs. 1
So 50 mangoes costs = Rs. 50
20% Profit on Selling Price of 10 mangoes = Rs. 12
30% Profit on Selling Price of 20 mangoes = Rs. 26
Total = Rs. 38
Loss = 50 - 38 = 12
Loss% = (12/50) x 100 = 24%.
