3

Number of those who studied at least 1 language=n(LUG)=15-3=12
Let Number of those who studied both languages=n(LnG)=x, then n(L)=7-x and n(G)=8-x
As n(LUG)=n(L) + n(G) - n(LnG)
12=(7-x) + (8-x) + x
=> x=3

There are 9 three digit numbers . Each number is reversed and the reversed number is subtracted from the original number. The results were found to have an average of 0. If for each number, hundreds digit is not less than its unit digit , find the average of the hundreds digit of the greatest and least numbers ?

Reply Like? Yes | No

Varun 6 years ago

101 is the least 3 digit number to have "hundreds digit not less than unit digit"

Result = 101-101 = 0

999 is the greatest 3 digit number.
Result = 999-999 = 0

Rest 7 numbers take any palindrome numbers like 252, 373, 444, 505, 666, 767, 868
Or any set giving average result zero like:
234, 432, 566, 775, 476, 988, 777

So required answer = (9-1)/2 = 5

Devendra Marghade 6 years ago

1. 10

Let number of students who passed in both=x, then
Students who passed only English=30-x and only maths=20-x
So required difference=Only English - Only Maths = (30-x) - (20-x) = 10

A basketball player played nine matches. The average number of points he scored per match was 16. His points in the ith match were two less than that in (i-1)th match. Find the average number of points scored in the second and eighth matches ??

Reply Like? Yes | No

Varun 6 years ago

Let points scored in first match be x

Then, his points are:
x, x-2, x-4,..., x-14, x-16
Average = [9x- 2(1+2+3...+8)]/9
= [9x-2(8*9)/2]/9
= [9x-72]/9
= x-8 = 16...., Given
=> x = 24
So second match score = 24-2 = 22
Eight match score = x-14 = 24-14 =10
Average points = (22+10)/2
= 16

There are N students in a class.their class teacher gave them a task of finding the average of the first N natural numbers and each of them left out a different number and found the average of remaining numbers.the average of the averages obtained by all the students was 21.find N .

Reply Like? Yes (1) | No

Manav 6 years ago

sum of sum of numbers given by all N students = N*( 21*(N-1) )

Each student leaves 1 number,,,
let the numbers left by students be k1,k2,k3, ....,kn,,,,so for student1 it will be

21(N-1) = sum of N numbers - k1

=N(N+1)/2 - k1

for every student, it will be N(N+1)/2 - ki
Adding sum obtained by all N students , we get

N*( 21*(N-1) ) = N* ( N(N+1)/2 ) - (k1 -k2 ...... -kn)

adding k1 to kn, we get sum of N numbers

so it will be,, 21*N*(N - 1 ) = (N - 1)*N*(N+1)/2

solving it, we get N=41

Based on investment , profit ratio = 15000*12: 10000*4= 18:4 = 9:2
If total profit is x, then profit after commissioning = 0.75x which is distributed in ratio of 9:2.
Total profit, x= Rs. 72368.42
profit of B= 72368.42-62500= Rs. 9868.42
