A. 10
B. 12
C. 15
D. 16

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Solution:

Let the two number is x and y,

Given that,
5x = 6y………..(i) ; (here x is the bigger one)
x + y = 22 ……(ii)

Now, from equation (ii),
x + y = 22
=> 6x + 6y = 22*6 ; ( Multiplying both sides by 6)
=> 6x + 5x = 132 ; ( from equation (i) )
=> 11x = 132
=> x =132 / 11
=> x = 12

Let,
the three numbers are x, x+1, x+2

Here, two smaller numbers are x, x+1 respectively

The sum of three consecutive number is 3X+3 = 123
so, X= (123-3)/3
= 40
Two smallers numbers are 40 and 41 respectively
So their product is 40*41
= 1640

Explanation:

ATQ,
x + y = 22 ... (i)
x2 + y2 = 404 ... (ii)
Therefore, (x + y)2 = x2 + y2 + 2xy
(22)2 = 404 + 2xy
484 = 404 + 2xy
Or, 2xy = 80
Or, xy = 40

Answer: Option D

Explanation:

Let's the two numbers are x and y. wher x>y

x + y = 23....(i)

and x - y = 21......(ii)

or, x - y = 21

or, x = 21 + y....(iIi)

replacing x with x = 21 + y in equation (i)

x + y = 23

or,21 + y + y = 23

or, 21 + 2y = 23

or, 2y = 2

∴ y = 1

so, the smallest number is 1

A. 12%
B. 14%
C. 16%
D. 18%

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Hints : Let the numbers be x and y

x + y = 28/25 × x

y = 28x /25 - x

y = 28x - 25x /25

y = 3x /25

So the second number is 3x /25

Now, percentage = 3x/25/x × 100 = 3x/25 × 1/x × 100% = 12%
