1
Out of two numbers, 4 times the smaller one is less than 3 times the larger one by 5, If the sum of the numbers is larger than 6 times their difference by 6, find the two numbers.
» Explain it
C
Let the number be x and y, such that x > y .

Then, 3x – 4y = 5       ....(1)  and  (x + y) – 6 (x – y) = 6

⇒  – 5x + 7y  = 6    .....(2)

Solving (1) and (2), we get : x = 59 and y = 43.

Hence, the required numbers are 59 and 43.

Hence, option C is correct.

2
Acid and water are mixed in a vessel A in the ratio of 5 : 2 and in the vessel B in the ratio 8 : 5. In what proportion should quantities be taken out from the two vessels so as to form a mixture in which acid and water will be in the ratio of 9 : 4?
» Explain it
A
By alligation method: ∴   Required ratio = 1 : 2 = 7 : 2 13 91

Hence, option A is correct.

3
Two trains, A and B start from the stations X and Y towards each other. They take 4 hours 48 mins and 3 hours 20 mins to reach Y and X respectively after they meet. If train A is moving at 45 km/hr, then the speed of train B is
» Explain it
C
Let the speed of Train A be SA = 45 kmph and that of Train B be Sb

Then, time taken by Train A = TA

 = 4 hrs 48 min = 4 + 48 = 24 hrs 60 5

Time taken by Train B = TB

 = 3 hrs 20 min = 3 + 20 = 10 hrs 60 3

Using formula  SA  =
 TB TA
SB

Note: If two trains (or bodies) start at the same time from points A and B towards each other and after crossing they take a and b sec in reaching B and A respectively, then

(A's spped) : (B's speed) = (b : a).

∴     45  =
 10 × 5 3 24
=
 25 36
=  5
SB 6

 or, SB = 45 × 6 = 54 kmph 5

Hence, option C is correct.

4
A shopkeeper deals in milk and 45 litre mixture is to be distributed in Milk & Water in the ratio of 4 : 1. If 4 litre milk & 3 litre water will be added in the mixture then what will be the new ratio of water and milk?
» Explain it
B
In the mixture of 45 litre,

 Milk = 45 × 4 = 36 litre, Water = 45 × 1 = 9 litre 5 5

New ratio = 9 + 3 : 36 + 4

= 12 : 40 = 3 : 10

Hence, option B is correct.

5
There are 4 cotton kurties, 3 woolen kurties and 5 nylon kurties. If 3 kurties are selected at random, what is the probability that none of them are nylon kurties?

» Explain it
C
3 kurties out of 12 kurties can be chosen in 12C3 ways

As given in the question above that we don't have to choose any nylon kurti

we have to select 3 kurties out of the remaining 7 kurties.

This can be done in 7C3 ways

 ∴  Reqd. probability = 7C3 12C3

 = 7 × 6 × 5 = 7 12 × 11 × 10 44

Hence, option C is correct.
