#### Question No 1

The ages of two persons differ by 16 years. 6 years ago, the elder one was 3 times as old as the younger one. What are their present ages of the elder person?

Solution!
Let's take the present age of the elder person = x

and the present age of the younger person = x - 16

(x - 6) = 3 (x-16-6)
x - 6 = 3x - 66
2x = 60
x = 60/2 = 30.

#### Question No 2

0 , 1 , 4 , 9 , 16 , 25 , 36 , 49 , ?

Solution!
Add 1, 3, 5, 7, etc..

#### Question No 3

What is average of 2, 5 , 6 , 9 and 18?

Solution!
(2+5+6+9+18)/5 = 40/5 = 8.

#### Question No 4

3 years ago, the average age of C and D was 18 years. With E joining them, the average becomes 22 years. How old is E now?

Solution!
Given that
[(C-3)+(D-3)]/2 = 18
C-3+D-3 = 36
C+D = 42 ...(1)

and also given that
(C+D+E)/3 = 22
C+D+E = 66

Put value of C+D from equation(1)
42+E = 66
E = 66-42
E = 24

Hence E is 24 years old now..

#### Question No 5

A train travelling at he speed of 72km/h can cross a platform in 17 seconds. If length of the train is 180 meters, what is the length of the platform?

Solution!
Speed of train = v = 72Km/h = 72*(5/18) = 20m/s

Time = t = 17s
Length of the train = L1 = 180m
Length of the platform = L2 = ?

t = (L1+L2)/v
By putting values
17 = (180+L2)/20
340-180 = L2
L2 = 160m

Hence length of the platform is 160m..

An article was bought for $300 and sold at a loss of 8%. What is the selling price of the article? #### Select the correct answer Solution! 8% of 300 = (300*8)/100 = 24 Selling price = 300-24 = 276. #### Question No 11 Find the odd man out. #### Select the correct answer Solution! Cretin is a biological term while all other are behaviour.. #### Question No 12 By selling an article for$84 shopkeeper earns 12% profit. What was cost price of the article?

Solution!
Let cost price of the article is x.
12% of x = 12x/100 = 3x/25

Now
84 - (3x/25) = x
2100 - 3x = 25x
2100 = 28x
x = 75

Hence cost price of the article is \$75..
