Q:

The cost price of a college bag is 240% more than the profit obtained on it selling at Rs. 1540. What is the cost price of that college bag?

A) Rs. 1190	B) Rs. 1288
C) Rs. 1365	D) Rs. 1452

Answer & Explanation Answer: A) Rs. 1190

Explanation:

Let the profit be Rs. p

Then Cost price of the bag = 340p/100 = 3.4p

According to question,

3.4p + p = 1540

4.4p = 1540

p = 1540/4.4

p = 350

The profit p = Rs, 350

Hence, The cost price of the bag = 3.4p = 3.4 x 350 = Rs. 1190.

Q:

A group of five persons is formed from five boys and four girls. Find the probability that there are at least two girls in the group?

A) 110/129	B) 5/6
C) 121/126	D) 3/7

Answer & Explanation Answer: A) 110/129

Explanation:

Total number of possible ways =

$9 C_{5} = \frac{9 x 8 x 7 x 6 x 5}{5 x 4 x 3 x 2 x 1} = 126$

Number of favorable cases =

$4 C_{2} x 5 C_{3} + 4 C_{3} x 5 C_{2} + 4 C_{4} x 5 C_{1} \frac{4 x 3}{2 x 1} x \frac{5 x 4 x 3}{3 x 2 x 1} + \frac{4 x 3 x 2}{3 x 2 x 1} x \frac{5 x 4}{2 x 1} + 1 x 5 = 6 x 10 + 4 x 10 + 5 = 60 + 40 + 5 = 105$

Therefore, required probability = 105/126 = 5/6
