Question 3 of 5
3. Question
A team of 11 is to be selected from 7 batsmen and 6 bowlers available. The team must have at least 5 bowlers. In how many ways can it be done?
Correct
Solution: D) 63
As the team must have at least 5 bowlers, two cases are possible:
Case I: Team has 5 bowlers out of 6 bowlers and 6 batsmen out of 7 batsmen. Number of ways of choosing such a team = Number of ways of choosing 5 bowlers out of 6 and 6 batsmen out of 7 = 6C5 * 7C6 = 6 * 7 = 42.
OR
Case II: Team has 6 bowlers out of 6 bowlers and 5 batsmen out of 7 batsmen. Number of ways of choosing such a team = Number of ways of choosing 6 bowlers out of 6 and 5 batsmen out of 7 = 6C6 * 7C5 = 1 * 21 = 21.
Hence, total ways possible = 42 + 21 = 63.Hence, option (d) is correct.
Incorrect
Solution: D) 63
As the team must have at least 5 bowlers, two cases are possible:
Case I: Team has 5 bowlers out of 6 bowlers and 6 batsmen out of 7 batsmen. Number of ways of choosing such a team = Number of ways of choosing 5 bowlers out of 6 and 6 batsmen out of 7 = 6C5 * 7C6 = 6 * 7 = 42.
OR
Case II: Team has 6 bowlers out of 6 bowlers and 5 batsmen out of 7 batsmen. Number of ways of choosing such a team = Number of ways of choosing 6 bowlers out of 6 and 5 batsmen out of 7 = 6C6 * 7C5 = 1 * 21 = 21.
Hence, total ways possible = 42 + 21 = 63.Hence, option (d) is correct.

Question 4 of 5
4. Question
The monthly income of Ramesh and Suresh are in the ratio 4:3 and the ratio of their expenditure is 3:2. If each of them saves Rs. 6000 then by what percentage is Ramesh income more than that of Suresh income?
Correct
Solution: B) 33.33%
Let the income of Ramesh and Suresh be 4x and 3x respectively
And the Expenses of Ramesh and Suresh are 3y and 2y respectively.
As it is given that each of them saves Rs. 6000 monthly.Therefore,
Savings of Ramesh = 4x – 3y = 6000 ……(Eq 1)
Saving of Suresh = 3x 2y = 6000 …….(Eq 2)
Subtracting (2) from (1) gives
x –y = 0, i.e. x = y …………….(Eq 3)
Using (Eq 3) in (Eq 1) we get, x = 6000.
So, Ramesh’s Income = 4x = 24000
Suresh’s income = 3x =18000
Net difference = 24000 – 18000 = 6000
Required percentage = 6000/18000 × 100% = 33.33%
Hence, option (b) is the correctIncorrect
Solution: B) 33.33%
Let the income of Ramesh and Suresh be 4x and 3x respectively
And the Expenses of Ramesh and Suresh are 3y and 2y respectively.
As it is given that each of them saves Rs. 6000 monthly.Therefore,
Savings of Ramesh = 4x – 3y = 6000 ……(Eq 1)
Saving of Suresh = 3x 2y = 6000 …….(Eq 2)
Subtracting (2) from (1) gives
x –y = 0, i.e. x = y …………….(Eq 3)
Using (Eq 3) in (Eq 1) we get, x = 6000.
So, Ramesh’s Income = 4x = 24000
Suresh’s income = 3x =18000
Net difference = 24000 – 18000 = 6000
Required percentage = 6000/18000 × 100% = 33.33%
Hence, option (b) is the correct 
Question 5 of 5
5. Question
To five liter of 20% sulfuric acid, seven and half liter of 80% sulfuric acid is added. What is the strength of the acid in the mixture now?
Correct
Solution: A) 56%
Percentage strength of the acid in the mixture = Quantity (volume) of the acid in the mixture/Total volume × 100
= [(5*20/100) + (7.5*80/100)/(5+7.5)] *100 = (5*20+7.5*80) /(5+7.5) = 56%.Hence, option (a) is correct.
Incorrect
Solution: A) 56%
Percentage strength of the acid in the mixture = Quantity (volume) of the acid in the mixture/Total volume × 100
= [(5*20/100) + (7.5*80/100)/(5+7.5)] *100 = (5*20+7.5*80) /(5+7.5) = 56%.Hence, option (a) is correct.
