3187 . The sum of two numbers is 22 and the sum of their squares is 404, then the product of two numbers is -

A. 40
B. 44
C. 80
D. 88

View Answer	Favorite Question

Answer: Option A

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

3190 . The sum of two numbers is 28/25 of the first number. The second number is what percent of the first ?

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

View Answer	Favorite Question

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%

E. None of these

View Answer	Favorite Question

Answer: Option D

Explanation:

let, the larger number = x

smaller number = x - 56

atq,

3(56 - x) = x/2

or,7x/2 = 168

or,x = 24*2 = 48

so, the larger number is = 48 (ans)

View Answer	Favorite Question

Answer: Option B

Explanation:

ধরি, সংখ্যা দুটি x ও y ; যেখানে x>y

x + y = 3 ( x - y)

x + 10 = 3 ( x - 10)

x + 10 = 3x - 30

2x = 40

x = 20

3194 . The sun of daily income of P, Q and R is Tk.90. If Q earns taka 10 more than P and R earns double of what Q earns, then what is the average of daily income of P and Q?

A. 40 Tk.
B. 30 Tk.
C. 20 Tk.
D. 10 Tk.

View Answer	Favorite Question

Answer: Option C

Explanation:

P+Q+R = 90 tk

Q = 10+P

R = 2Q = 2(10+P) = 20+2P

P+Q+R = 90

P+10+P+20+2P = 90

P = 15

So, Q = 10+P = 10+15 = 25

Now, P+Q = 15+25 = 40

Average of P and Q is = 40/2 = 20 (Ans)
