Aptitude - Percentage - Discussion

Before we solve the problem, note these basic points.

1. Percentage is a method of expressing fractions or parts of any quantity into an equivalent form. The term per cent means for every hundred.

2. 100% means 100 hundredths or 100/100 = 1.50% means 50 hundredths or 50/100 = 1/2 or 0.5.

3. How many 40 Rs. are in 100 Rs? Yes, it is 40 Rs only. (Rs. 40 = 40 one rupees).

4. We can also form a question like, what percent is 40 rupees of 100 rupees. Answer. (40/100) *100 = 40.

Lets generalize here.

1. When we need to find x of y, we simply write as x/y.

2. When we need to find x% then, we simply write as x/100.

3. When we need to find x% of y, then x/y/100 therefore we can write it as (x/y)*100.

Now lets solve the problem.

1. The batman scored 110 runs. Out of which he scored by 3 boundaries (3*4=12 runs) , 8 sixes (8*6=48 runs).

2. In the question, they are asking the percentage of runs he scored by running. Simple, we will just minus the 60 runs (12+48) from 110.

3. Therefore, the runs he obtained by running is 50 (110-60).

4. To find what percent is 50 of 110 = (50/110) *100 = 500/11. This gives a final result 45*5/11. {Quotient* (remainder/division) = 45*5/11}.

Any shortcut method for this kind of problem.

There are five digit integers a, b, c, d, e in ascending order.

(68-a)(68-b)(68-c)(68-d)(68-e) = 725 what is a+b+c+d?

Why we are divide 50/110 instead of 110/50?

Tell some easy tricks which can be easily catched by everyone & in a short time.

How did you get 4 and 6?

3*4 n 8*6?

How to this answer 20.45?

Total boundaries and sixes are (3*4+8*6) = 60.

So the remaining score is running between the wicket.

i.e.110-60 = 50. Then we have to find 50 is what % of 110.

So the answer is 50/110*100 after solving this answer is 45 5/11%.

So the answer is 50/110*100 after solving this answer is 45 5/11%.

In a fraction, the number is increased by 20% and the denominator is decreased by 10% then the value of the fraction becomes 5/7. Then find the original fraction?
