Just 50/100 is not correct?

When we divide 500 by 11 then we get 45 as answer and 5 as remainder so B is the answer.

I really clear and thx Aparna

Runs=110;
fours=4*3=12;,sixes=8*6=48;
total=48+12=60;
110-60=50;
100=110
?=50;
45.51..

Why we need to divide 50/110?

In order to find the percentage of runs scored by running the wickets.

see the total runs scored by the batsman is 110.
runs scored by fours and sixes is 4*3+6*8=60

then runs scored by running b/w wickets = 50(total runs(110) - runs scored by fours and sixes(60))

for 110 runs if he scored 50 runs by running b/w wickets
then for 100 how much

this can written in the ratio form as 110:100::50:X
then x=(100*50)/110
solving we get the answer as 500/11
converting in mixed fraction we 45*5/11.

i hope u understood.. have a nice day.

3*4=12,
8*6= 48
48+12=60

Total run b/w the wickets 110 - 60=50

Therefore %= 50/110* 100 = 45.454545

In what ratio should wheat at Rs. 4.5 per kg be mixed with another variety at Rs. 5.25 per kg so that the mixture be worth of Rs. 5 per kg?

a. 1:2
b. 2:1
c. 1:3
d. 3:1.

Please anybody tel the answer with explanation.

3*4+8*6=60.

So answer will be (C).

An important interview question:

Question: 75% of a number when added to 75 becomes the number itself. The number is ?

Solution:

Let the required number be x.

x = 75% of x + 75

x = 75/100x + 75

1x = 0.75x + 75

1x - 0.75x = 75

0.25x = 75

x = 75/0.25

x = 7500/25

x = 300.

Verification:

75% of 300 = 275
Now 755 + 75 = 300

Hence 300 is the required answer.
