In a group of 70 people, 37 like coffee, 52 like tea and each person likes at least one of the two drinks. How many people like both coffee and tea?
A)
9
B)
10
C)
18
D)
19
Use the inclusion-exclusion principle. Let C = people who like coffee and T = people who like tea.
Given:
|C| = 37, |T| = 52, and every one of the 70 people likes at least one drink, so |C ∪ T| = 70.
Now,
|C ∪ T| = |C| + |T| - |C ∩ T|
70 = 37 + 52 - |C ∩ T|
70 = 89 - |C ∩ T|
|C ∩ T| = 19
So the correct answer is 19, which corresponds to option (d).
Note: The option list shows 19 as (d), so the expected answer is 19.

A bag contains 35 balls of which x are red, 2x are white and 4x are blue. A ball is selected at random. What is the probality that it is red?
A)
1/7
B)
1/8
C)

Let the number of red balls be x, white balls 2x, and blue balls 4x. Then total balls = x + 2x + 4x = 7x. Given total balls are 35, so 7x = 35 and x = 5. Therefore, probability of selecting a red ball = red balls / total balls = 5/35 = 1/7. Hence, the correct option is (a).

A smart phone is available for Rs. 25000 cash or Rs. 10000 cash down payment along with two equal annual instalments of Rs. 8000 each, then the total interest charged is -
A)
Rs. 1700
B)
Rs. 1500
C)
Rs. 1000
D)
Rs. 2500
Cash price = Rs. 25,000. Under the instalment plan, down payment = Rs. 10,000 and two annual instalments of Rs. 8,000 each, so total paid = 10,000 + 8,000 + 8,000 = Rs. 26,000. The total interest charged is the extra amount paid over the cash price: 26,000 - 25,000 = Rs. 1,000. Therefore, the correct answer is Rs. 1,000, which corresponds to option (c).
