Q:

If selling price is doubled, the profit triples. Find the profit percent ?

A) 100% B) 200%
C) 300% D) 400%
 
Answer & Explanation Answer: A) 100%

Explanation:

Let the C.P be Rs.100 and S.P be Rs.x, Then
The profit is (x-100)
Now the S.P is doubled, then the new S.P is 2x
New profit is (2x-100)
Now as per the given condition;
=> 3(x-100) = 2x-100
By solving, we get
x = 200
Then the Profit percent = (200-100)/100 = 100
Hence the profit percentage is 100%

17, 9, 10, 18.5, 35, 90

A) 9 B) 10
C) 18.5 D) 90
 
Answer & Explanation Answer: C) 18.5

Explanation:

The given series pattern follows

× 0.5 + 0.5,   × 1 + 1,   × 1.5 + 1.5,   × 2 + 2,   × 2.5 + 2.5

 

So here 

 

17x0.5 + 0.5 = 9

 

9x1 + 1 = 10

 

10x1.5 + 1.5 = 16.5

 

16.5x2 + 2 = 35

 

35x2.5 + 2.5 = 90

 

Here the odd man in the given series is 18.5
