Arithmetical Reasoning section 2 MCQ
Question : 11
Between two book-ends in your study are displayed your five favourite puzzle books. If you decide to arrange the five books in every possible combination and moved just one book every minute, how long would it take you?
a) 3 hours
b) 1 hour
c) 2 hours
d) 4 hours
Answer »Answer: (c)
Clearly, number of ways of arranging 5 books = 5!
= 5 × 4 × 3 × 2 × 1 = 120
So, total time taken = 120 minutes = 2 hours.
Question : 12
Five bells begin to toll together and toll respectively at intervals of 6, 5, 7, 10 and 12 seconds. How many times will they toll together in one hour excluding the one at the start ?
a) 9 times
b) 7 times
c) 8 times
d) 11 times
Answer »Answer: (c)
L.C.M. of 6, 5, 7, 10 and 12 is 420.
So, the bells will toll together after every 420 seconds i.e. 7 minutes.
Now, 7 × 8 = 56 and 7 × 9 = 63.
Thus, in 1-hour (or 60 minutes), the bells will toll together 8 times, excluding the one at the start.
Question : 13
There are four routes to travel from city A to city B and six routes from city B to city C. How many routes are possible to travel from the city A to city C ?
a) 10
b) 24
c) 12
d) 8
Answer »Answer: (b)
Total number of possible routes from the city A to city C = 4 × 6 = 24
Question : 14
At a dinner party every two guests used a bowl of rice between them, every three guests used a bowl of daal between them and every four used a bowl of meat between them. There were altogether 65 dishes. How many guests were present at the party ?
a) 90
b) 60
c) 65
d) None of these
Answer »Answer: (b)
Let the number of guests be x. Then number of bowls of rice = $x/2$; number of bowls of dal = $x/3$; number of bowls of meat = $x/4$.
∴ $x/2 + x/3 + x/4$ = 65
⇔ ${6x + 4x + 3x}/{12}$ = 65 ⇔ 13x = 65 × 12
⇔ x = $({65 × 12}/{13})$ = 60
Question : 15
A man wears socks of two colours - black and brown. He has altogether 20 black socks and 20 brown socks in a drawer. Supposing he has to take out the socks in the dark, how many must he take out to be sure that he has a matching pair ?
a) 39
b) 3
c) 20
d) None of these
Answer »Answer: (b)
Since there are socks of only two colours, so two out of any three socks must always be of the same colour.
