Question

if 15% of 40 is greater than 25%of a number by 2. find the number

Answer 1

Let the number be x.

Given that 15% of 40 is greater than 25% of a number by 2.

(0.15) * 40 - 2 = (0.25) * x

6 - 2 = 0.25x

4 = 0.25x

x = 4/0.25

x = 16.

Therefore the number is 16.


Hope this helps!

Answer 2

Question :-

if 15% of 40 is greater than 25%of a number by 2. find the number

Solution :-

Given that if 15% of 40 is greater than 25%of a number by 2. find the number .

Let the number be 'x'

• Then , the equation be like :-

$(0.15) \times 40 - 2 = ( 0.25 ) × x$

$-» 6 - 2 = 0.25x$

$-» 4 = 0.25x$

$-» x = \frac{0.25}{4}$

$-» x = 16$

∴The number is 16.

Verification :

if 15% of 40 is greater than 25%of a number by 2. find the number

• In place of x we will take 16

→ 15% if 40 is :-

$\frac{15}{100} \times 40$

• Cut of zero

$\frac{15}{10∅} \times 4∅$

Cut if 15 and 10 by 5

$\frac{3}{2} \times 4$

• Cut of 2 and 4 by 2

$\frac{3}{1} \times 2$

• Multiply 3 and 2

$3 \times 2 = 6$

Now , we will take 25% of 16

$\frac{25}{100} \times 16$

• Cut of 100 and 25 by 25
• Cut of 4 and 16 by 4

$= 4$

• The question saying by 2.

• So we will multiply 4 by 2

$4 \times 2$

$= 8$

∴ Hence , 8 is smaller than 6 so , the answer is correct.
