Solution

Given:

• We need to select a cricket team i.e. 11 players
o We need to select 5 batsmen from 7 batsmen and,
o We need to select 4 bowlers from 6 bowlers and,
o We need to select 1 wicket keeper from 3 wicket keepers and,
o We need to select 1 all-rounder from 3 all-rounders.

To find:
• The number of ways we can from a cricket team out of 7 batsmen, 6 bowlers, 3 allrounders and 3 wicketkeepers available.

Approach and Working:

Since we need to select 5 batsmen, 4 bowlers, and 1 wicket keeper and 1 all-rounder in the cricket team,
• Hence, number of ways to form the cricket team= ways to select 5 batsmen from 7 batsmen* ways to select 4 bowlers from 6 bowlers * ways to select 1 wicket keeper from 3 wicket keepers * ways to select 1 all-rounder from 3 all-rounders

• Thus, total ways= $$^7c_5$$*$$^6c_4$$*$$^3c_1$$*$$^3c_1$$

• =21*15*3*3= 2835

Hence, in 2835 ways we can select a cricket team.

Hence, option D is the correct answer.

Learn to use the Keyword Approach in Solving PnC question from the following article:

Article-1: Learn when to “Add” and “Multiply” in Permutation & Combination questions

Article-2: Learn structured approach to identify Permutation & Combination questions

A simple PS question where one has to choose 5 batsman from 7 batsman, 4 bowlers out of 6 bowlers, 1 wicket keeper out of 3 wicket keepers and 1 all rounder from 3 allrounders. So according to combinations principles, the number of ways we can choose r items from n items is found out as nCr which equals to n!/((n-r)!*r!). So here the solution is , 7C5*6C4*3C1*3C1 = 2835 (D)

It's a simple question of selection for which we use combination formula

7C5*6C4*3C1*3C1

Take the task of creating a cricket team and break it into stages and then apply the Fundamental Counting Principle

Stage 1: Select 5 batsmen
Since the order in which we select the batsmen does not matter, we can use combinations.
We can select 5 batsmen from 7 batsmen in 7C5 ways (21 ways)
So, we can complete stage 1 in 21 ways

Stage 2: Select 4 bowlers
Since the order in which we select the bowlers does not matter, we can use combinations.
We can select 4 bowlers from 6 bowlers in 6C2 ways (15 ways)
So, we can complete stage 2 in 15 ways

Stage 3: Select 1 wicketkeeper
There are 3 wicketkeepers from which to choose, so we can complete this stage in 3 ways.

Stage 4: Select 1 all-rounder
There are 3 all-rounders from which to choose, so we can complete this stage in 3 ways.

By the Fundamental Counting Principle (FCP), we can complete all 4 stages (and thus create a cricket team) in (21)(15)(3)(3) ways ( = 2835 ways)

Note: the FCP can be used to solve the MAJORITY of counting questions on the GMAT. So, be sure to learn it.
