The tank full of petrol in Haroon’s motorcycle lasts for 10 days, if he starts using 25% more every day for how many days will the tank full of petrol last?

A. 5days
B. 6days
C. 7days
D. 8days
Explanation:
Let us assume that Arun uses X units of petrol everyday.
So the amount of petrol in the tank when it is fuel will be 10X.
If he started using 25% more petrol every day, then the amount of petrol he how uses everyday will be
X (1 +25/100) =1.25x
Therefore, number of days his petrol will how last = Amount of petrol in tank / amount of petrol used everyday = 10x/1.25x = 10/1.25 = 8 Days

In a survey it was found that 80% of those surveyed owned a car while 60% of those surveyed owned a mobile phone, if 55% owned both a car and a Mobile phone, What percent of those surveyed owned a car or a mobile phone or both?

A. 65%
B. 80%
C. 85%
D. 97.5%
Explanation:
Given that percentage of car owners = 80%
Percentage of mobile phone owners = 60%
Percentage of people having both car and mobile phone = 55%
Percentage of people having only car = 80 -55 = 25%
Percentage of people having only mobile phone = 60 -55 =5%
Percentage of people having car or mobile phone or both = 55% + 25% + 5% = 85%
