Question 6 of 10
6. Question
A blind school has 3433 visually handicapped students. 80 to 85 percent of the students are good musicians and 30 to 40 percent of the students are good actors. Each student has excellence in at least one of the skills of music and acting. What is the absolute difference between the minimum and maximum possible numbers of students who are both great musicians and actors?
Correct
Solution:
Total Students = 2001
% of students who are musicians = 80% to 85% of 3433 = 2746 to 2918
So, % of students who are good in acting alone =100%85% to 100%80% = 15% to 20% = 515 to 687
% of students who are good actors = 30% to 45% = 1030 to 1545
So, minimum = 1030687=201
and maximum = 1545515=499
and 499201=298Incorrect
Solution:
Total Students = 2001
% of students who are musicians = 80% to 85% of 3433 = 2746 to 2918
So, % of students who are good in acting alone =100%85% to 100%80% = 15% to 20% = 515 to 687
% of students who are good actors = 30% to 45% = 1030 to 1545
So, minimum = 1030687=201
and maximum = 1545515=499
and 499201=298 
Question 7 of 10
7. Question
20 college students are waiting in a queue for discount coupons of KFC. Each coupon costs ₹5. Ten of the students have the ₹5 coin and others have currency notes of ₹10. Determine in how many ways can all the 20 students stand in the queue such that the person at the coupon counter will not face any issue in paying back changes provided that the person at the counter does not have any changes.
Correct
Solution:
For the coupon seller to have change always, the person with ₹5 should come before the person with ₹ 10
We can also say that first person must have ₹5 and 20th person must have ₹10
→ let us take this case 5_ _ _(10 places), 10 _ _ _ (10 places), no of cases – 1Take the first 10 numbers as one part and next 10 as second part
now take one 10 into the first part, this can be done in ^{9}C_{1 }ways because 1st number should be 5 always
and the 5 which is replaced by 10 can be arranged in ^{9}C_{1} ways in 2nd partone 10 is replaced, no of cases: ^{9}C_{1}x^{9}C_{1} = 81
now replace two 10’s , 5 5 _ _ _ _ _ _ _ _ ; ……..10 —– ^{8}C^{2} ways
5 10 5 _ _ _ _ _ _ _ ; …… 10 —– ^{7}C_{1} ways
same will be the cases for two 5’s to be arranged in the second part
two 10’s are replaced, no of cases – (^{8}C_{2} + ^{7}C_{1})x(^{8}C_{2} + ^{7}C_{1}) = 1225
replace three 10’s, 5 5 5 _ _ _ _ _ _ _; ……… 10 —— ^{7}C_{3} ways
5 10 5 5 _ _ _ _ _ _ ; ……… 10 ——– ^{6}C_{2} ways
5 10 5 10 5 _ _ _ _ _ ; …….. 10 —— ^{5}C_{1 }ways
three 10’s are replaced, no of cases – (^{7}C_{3} + ^{6}C_{2} + ^{5}C_{1})x(^{7}C_{3 }+ ^{6}C_{2} + ^{5}C_{1}) = 3025
four 10’s replaced , no of cases : (^{6}C_{4} + ^{5}C_{3} + ^{4}C_{2} + ^{3}C_{1})^{ 2} = 1156five 10’s replaced , no of cases : (^{5}C_{5 }+ ^{4}C_{4} + ^{3}C_{3} + ^{2}C_{2} + ^{1}C_{1}) ^{2} = 25
max only five 10’s can come into first part
so total number of cases = 1+81+1225+3025+1156+25= 5513Incorrect
Solution:
For the coupon seller to have change always, the person with ₹5 should come before the person with ₹ 10
We can also say that first person must have ₹5 and 20th person must have ₹10

max only five 10’s can come into first part
so total number of cases = 1+81+1225+3025+1156+25= 5513 
Question 8 of 10
8. Question
Arshi is a shopaholic. She went to a bag shop to buy a handmade wallet. She took ₹ 15 to the shop in the form of one rupee notes and 20 paise coins. After returning from the shop after buying the wallet, she was left with as many one rupee notes as she originally had 20 paise coins and as many 20 paise coins as she had originally one rupee notes. The total amount also reduced by twothird. What was the cost of the wallet?
Correct
Solution:
Let number of one rupee notes=X
Number of 20 paise coins=Y
Arshi started with (100X+20Y) and came back with (100Y and 20A) paise
Also, 100Y+20X=(1/3) (100X+20Y)
=>X=7Y
By hit and trial method,
Put Y=1=>X=7=>total ₹ 7.2 is less
Put Y=2=>X=14=>Total=₹ 14.4
This is correct.
Hence she spent=(2/3)x14.4=₹ 9.60=cost of wallet
Incorrect
Solution:
Let number of one rupee notes=X
Number of 20 paise coins=Y
Arshi started with (100X+20Y) and came back with (100Y and 20A) paise
Also, 100Y+20X=(1/3) (100X+20Y)
=>X=7Y
By hit and trial method,
Put Y=1=>X=7=>total ₹ 7.2 is less
Put Y=2=>X=14=>Total=₹ 14.4
This is correct.
Hence she spent=(2/3)x14.4=₹ 9.60=cost of wallet

Question 9 of 10
9. Question
In an island of the Maldives, the natives have a peculiar process of determining their average earnings and expenditures. According to an old tradition, the average monthly earnings had to be calculated on the basis of 14 months in the calendar year, while the average monthly expenditure was to be calculated on the basis of 9 months in the year. This weird system of calculation always resulted in the natives underestimating their savings because there occurs an underestimation of their earning. The expenditure per month gets overestimated. Now keeping the above points in view try to answer the below questions:
Mr. Ghosh comes to his native island from Africa and makes his native community comprising of 173 families to calculate their average earning and the average expenditure on the basis of 12 months per the calendar year. The average estimated earning in his community according to the old system is 77 fasios per month. Assuming there are no other changes, what will be the percentage change in savings of the 173 families?
Correct
Solution:
Average Monthly earning (old system) = 77
So, Total Income of 173 families/14 = 77
So, Total Income of 173 families = 77×14
Now,Average Monthly earning of 173 families (new system) =
Total Income/12 = 77×14/12 = 89.83 fasios
But, we do not know the average monthly expenditure in either system.
Nor do we know the savings.
So, the required answer cannot be determined.Incorrect

10. Question
In an island of the Maldives, the natives have a peculiar process of determining their average earnings and expenditures. According to an old tradition, the average monthly earnings had to be calculated on the basis of 14 months in the calendar year, while the average monthly expenditure was to be calculated on the basis of 9 months in the year. This weird system of calculation always resulted in the natives underestimating their savings because there occurs an underestimation of their earning. The expenditure per month gets overestimated. Now keeping the above points in view try to answer the below questions:
In the previous question, the average estimated monthly expenditure is 21 fasios per month for the island. Determine the percentage change in the estimated savings of the 173 families.
Correct
Solution:
Average Monthly Income (old system) = 77
So, Total Income of 173 families/14 = 77
So, Total Income of 173 families = 77×14
Now, Average Monthly Income of 173 families (new system) =Total Income/12 = 77×14/12 = 89.83 fasios
Now, Average Monthly expenditure (old system) = 21
So Average Monthly Expenditure (new system) = 21×9/12 = 15.75Total Savings (old system) = 7721=56
Total Savings (new system) = 89.8315.75 = 74.08
%change = (74.0856)/56 x100 = 32.3%Incorrect
Solution:
Average Monthly Income (old system) = 77
So, Total Income of 173 families/14 = 77
So, Total Income of 173 families = 77×14
Now, Average Monthly Income of 173 families (new system) =Total Income/12 = 77×14/12 = 89.83 fasios
Now, Average Monthly expenditure (old system) = 21
So Average Monthly Expenditure (new system) = 21×9/12 = 15.75Total Savings (old system) = 7721=56
Total Savings (new system) = 89.8315.75 = 74.08
%change = (74.0856)/56 x100 = 32.3%
