Question

In an examination 80% passed in English, 85% passed in
Mathematics but 75% passed in both the subjects. If only 45 examinees failed
in both the subjects then find the number of examinees.​

Answer 1

Answer:

$\orange{ \boxed{ \boxed{450 \: examinees}}}$

Step-by-step explanation:

$\red{ \mathfrak{ \large{Given}}}$

80 % passed in sub

85 % passed in maths

75 % passed in both

And 45 students failed in both.

$\green{ \mathfrak{ \large{Solution}}}$

Let there are X no of examines.

80% of X passed in sub = (80/100)*x =4x/5.

85% of X passed in maths=(85/100)*x=17x/20.

75% of X passed in both =(75/100)*x= 3x/4.

There students passed “only” in sub = students passed in sub - students passed in both

i.e 4x/5 - 3x/4 = x/20 .

Similarly, students passed only in maths

= 17x/20 - 3x/4 = x/10 .

There for total students passed = 3x/4 + x/20 + x/10 = 18x/20 = 9x/10 .

There for no of students failed = x - 9x/10 = x/10

And x/10 = 45 ( given in question)

So X = 450 .

Hence,There total examines in class is 450 .

The Boy Who Rode into the Sunset
Once upon a time — it was not so very long ago, either — a little boy, named Neville, lived to say, it was just at the edge of the city; and at the back of the house was a rather large hill, which was quite bald.
Neville, who was fond of playing by himself, would often wander to the top of the bald hill; and if he stood right on top of it and looked one way, toward the East, he could see right over the city, with all its tall buildings and domes and spires and smoking chimneys. But looking the other way, to the West, he could see for miles over the beautiful country, with its green fields and orchards and white roads and little farm houses.
One evening Neville was playing alone on the top of the hill when he noticed that one of the very finest sunsets he had ever seen was just coming on. The sky in the West, away over the broad country lands, was filled with little clouds of all sorts and shapes, and they were just beginning to take on the most wonderful colours.
Neville had often before amused himself with watching clouds and the strange shapes into which they changed themselves — sometimes like great mountain ranges, sometimes like sea-waves, and very often like elephants and lions and seals and all manner of interesting things of that sort. But never before had he been able to make out so many animal shapes in the clouds. The sky was almost as good as a Zoo. There were kangaroos and elephants and a hen with chickens and wallabies and rabbits and a funny man with large ears and all sorts of other peculiar shapes.
The sun was sinking behind a distant range of hills, where a golden light shone out as if through a gateway. It was so much like a great golden gateway that Neville fell to wondering what might be found on the other side of it.
Suddenly, right in the middle of all the coloured clouds, he saw one little cloud which was perfectly white, and, as he watched it, he noticed that it seemed to be shaped like a small horse. A very small horse it seemed at that distance; but, as Neville gazed, it grew bigger and bigger, just as if it were coming toward him very fast, and he was almost certain he could see its legs moving.
