Directions: Read the following questions carefully and choose the right answer.
Important for :
1
Wangdu purchased 20 identical items from a wholesaler. He marked the price of each item at 110% of the cost price. However, on Diwali, he gave a discount of 10% to all customers. Phunshuk bought 2 items at Rs. 396 on Diwali. What was the marked price of each item? (Assume that Wangdu sells only these 20 items.)
» Explain it
C
Since Phunshuk bought 2 items for Rs. 396,

SP per item =  396  = Rs. 198
2

Since this SP is after a 10% discount on MP, MP of each item 90% of MP = SP

MP =  SP  =  198  = Rs. 220
0.9 0.9

Hence, option C is correct.
2
The average weight of employees of a company is 72.5 kg while the weight of their immediate senior is 66.66% less than the average weight of the employees. If the weight of immediate senior is x kg, what is the total weight of the employees?
» Explain it
D
Weight of immediate senior = 66.66% less than average weight of employees = 33.33% of average weight of employees.
 
∴   Average weight of employees = 3 × weight of immediate senior = 3x
 
Since number of employees in the office is not known, total weight can't be determined. 
 
Hence, option D is correct.
3
The probability that Arjun hits the fish’s eye in one try is 1/2. How many tries does he need so that the probability of hitting the fish’s eye atleast once is 0.9 ?
» Explain it
A
Since P (hitting the target in one try) = 0.5, P (not hitting the target in one try) = 1 − 0.5 = 0.5

Let Arjun have tried n times.

∴  P (Arjun hit atleast once) = 1 − P (Arjun did not hit in any try) = 1 − (0.5)n

∵  P (Arjun hit atleast once) ≥ 0.9; 1 − (0.5)n ≥ 0.9

∴  (0.5)n ≤ 0.1

This is first satisfied for n = 4 i.e. (0.5)4 = 0.0625

Therefore, Arjun needs atleast four tries.

Hence, option A is correct.
4
A man swimming downstream covers a distance of 30 km in 2 hours. When he swims back, he takes 6 hours to cover the same distance. If the speed of the current is half that of the man, what is the speed of the man? (in km/h)
» Explain it
E
As per the given information, we get

Upstream speed =  30  = 5 km/hr
6

Downstream speed =  30  = 15 km/hr
2

∴   Speed of the boat =  5 + 15  = 10 km/hr
2

Hence, option E is correct.
5
A man is 3 times faster than a woman to finish a certain piece of work. If a woman can finish the work in 20 minutes, then how long will it take to finish the work if both man and woman start working together?
» Explain it
B
A woman can finish  1  of the work in 1 minute
20

A man can finish  3  of the work in 1 minute
20

If both start working together then in one minute they will finish
 
  ( 1  +  3 i.e.  1  of the work
20 20 5

So, they will take 5 minutes to finish the work.

Hence, option B is correct.
