Q:

An owner of a Dry fruits shop sold small packets of mixed nuts for Rs. 150 each and large packets for Rs. 250 each. One day he sold 5000 packets, for a total of Rs. 10.50 lakh. How many small packets were sold ?

A) 2000 B) 3000
C) 2500 D) 3500
 
Answer & Explanation Answer: A) 2000

Explanation:

Let 's' be the number of small packets and 'b' the number of large packets sold on that day.

 

Therefore, s + b = 5000 ... eqn (1)

 

Each small packet was sold for Rs.150.
Therefore, 's' small packets would have fetched Rs.150s.

 

Each large packets was sold for Rs.250.
Therefore, 'b' large packets would have fetched Rs.250b.

 

Total value of sale = 150s + 250b = Rs. 10.5 Lakhs (Given)

 

Or 150s + 250b = 10,50,000 ... eqn (2)

 

Multiplying equation (1) by 150, we get 150s + 150b = 7,50,000 ... eqn (3)

 

Subtracting eqn (3) from eqn (2), we get 100b = 3,00,000
Or b = 3000

 

We know that s + b = 5000
So, s = 5000 - b = 5000 - 3000 = 2000.

 

2000 small packets were sold.

Q:

A box contains 2 blue balls, 3 green balls and 4 yellow balls. In how many ways can 3 balls be drawn from the box, if at least one green ball is to be included in the draw?

A) 48 B) 24
C) 64 D) 32
 
Answer & Explanation Answer: C) 64

Explanation:

Total number of balls = 2 + 3 + 4 = 9

Total number of ways 3 balls can be drawn from 9 = 9C3

No green ball is drawn = 9 - 3 = 6 = 6C3

Required number of ways if atleast one green ball is to be included = Total number of ways - No green ball is drawn

= 9C3 - 6C3

= 9x8x7/3x2  -  6x5x4/3x2

= 84 - 20

= 64 ways.
