Ina school,out of 450 students of a school, 325 play football, 175 play cricket and 50 neither play football nor cricket. How many students play both football and cricket ?

1)	65	2)	80
3)	100	4)	120
5)	None of these

Answer : 100

Students who play cricket, n(A) = 325

Students who play football, n(B) = 175

Total students who play either or both games, = n(A∪B) = 450 − 50 = 400

Required Number,n(A∩B) = n(A)+n(B)−n(A∪B) = 325+175−400 = 100

In an examination, 34% of the students failed in mathematics and 42% failed in English. If 20% of the students failed in both the subjects, then find the percentage of students who passed in both the subjects.

1)	36%	2)	40%
3)	44%	4)	45%
5)	None of these

Answer : 44%
Explanation :

Students failed in mathematics, n(A) = 34

Students failed in English, n(B) = 42

n(A∪B)= n(A)+n(B)−n(A∩B) = 34+42−20=56

Failed in either or both subjects are 56

So % passed = (100−56)% = 44%

Alok bought a table and paid 10 % less than the original price. He sold it with 30% profit on the price he had paid. What percentage of profit did he earn on the original price ?

1)	12%	2)	15%
3)	16%	4)	17%
5)	None of these

Answer : 17%
Explanation :

Let, the original price =100

Then the price at which he purchased (CP) = 90% of 100 = 90

Profi t = 30%

So, S.P = (90 /100) x 130 = 117

Thus, profit % = (117 - 100)/100 = 17%

Q406.

A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. What is his profit percentage ?

1)	4%	2)	5%
3)	6%	4)	8%
5)	None of these

Answer : 5%
Explanation : CP of 1st variety rice = 20

CP of 2nd variety rice =36

CP of the 56 kg rice mixture = (26�20+30�36) = 520 + 1080 = 1600

SP of the 1 kg rice mixture = 30

SP of the 56 kg rice mixture = 30�56 = 1680

Gain = SP − CP = 1680 − 1600 = 80

Gain % = (Gain x CP) � 100 = (80/1600 )�100 = (100/20) = 5%
