Q 1 - A car driver spends Rs 20 for each km for traveling in bus, and spends 10 less for his own drive. In one week, he pays Rs. 800 for travelling 60km. How many km did he travel on his own?
Let distance travelled by bus=X
Distance covered by his own = 60- (20X + 10(60-X)) = 800X = 2
Q 2 - Ramesh’s salary as a waiter consists of his basic salary and tips from customers. During one week his tips were 3/4 of his basic salary. What fraction of his income came from tips?
Let basic salary = z, tips = 3z/4
Total income = z + 3z/4 = 7z/4
Required fraction = 3z/4 / 7z/4 = 3/7
Q 3 - In between two file ends in the rack are six paper weights. If you decide to arrange the six paper weights in every possible combination and moved just one paper weight every minute, how long would it take to you?
Clearly, we can get the answer by taking the factorial.
= 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720.
So total time taken = 720 minutes = 12 hours.
Q 4 - Mr. Sharma has a cattle farm of his own. And in his farm there are goats and hens. In that group of goats and hens, the number of legs are more than twice the number of heads. The number of goats is
Data is inadequate to get to any conclusion.
Q 5 - In Cuttack in an Odia family, Mr. Pattnaik has a son and a daughter. They are Pratush and Pratyasha. The age of Mr. Pattnaik is three times that of his daughter Pratyasha and the age of Pratush is half of that of his mother. Mrs. Pattnaik is 9 years younger to her husband and Pratush is seven years older than his sister Pratyasha. What is the age of Mrs. Pattnaik?
Let Pratyasha’s age be x years.
Then, Mr. Pattnaik’s age = 3x years.
Mrs. Pattnaik’s age = (3x – 9) years; Pratush’s age = (x + 7) years.
So, x + 7 = (3x - 9)/2 2x + 14 = 3x – 9 x = 23.
Therefore Mrs Pattnaik’s age = (3X – 9) = (69 – 9) years = 60 years.
Q 6 - 16 men and 20 boys can do a piece of work in 30 days. In how many days, 15 men and 15 boys will take to finish the work?
16 men = 20 boys
1 man = 5/4 boys
15 men = 75/4 boys
Total no of boys = 75/4 + 15 = 135/4
20 boys = 30 days
135/4 boys = 30 × 20 × 4 /135 = 17 7/9 days
Q 7 - There is a business conference in the HFl financial services. This meeting is normally held once in two months and 10 board members of the institution attend the meeting. At the closing of an important business conference, ten people those were present in the meeting shake hands with each other once. How many handshakes will there be altogether?
Clearly, total number of handshakes = (9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1) = 45.
Q 8 - Ravi Kumar is preparing for a city walkathon for which he usually starts at 5 am in the morning. Walking at the rate of 4kmph Ravi covers certain distance in 2hr 45 min. Running at a speed of 16.5 kmph he can cover the same distance in
After putting the relationship of distance time and speed we can get the answer as 40 minutes.
Q 9 - Five students in a tuition have done mathematics in an examination. Each has secured a different number. and the numbers are 54, 48, 90, 67, and 88. Find the average.
The average is = (54 + 48 + 90 + 67 + 88)/5 = 347/5 = 69.4.
Q 10 - Mr. Das told his son Rinku in a special occasion that, he was of Rinku’s current age when Rinku was born. If Mr Das is 36 now, how old was Rinku five years back?
Let Rinku’s father’s age be x and the Rinku’s age be y.
Then, x – y = y or x = 2y
Now, x = 36. So, 2y = 36 or y = 18.Therefore Rinku’s present age = 18 years. So, Rinku’’s age 5 years ago = 13 years.
