Answer 2

Answer:

15% of A is equal to 18% of B.      

Step-by-step explanation:

Given : If 10% of A is equal to 12% on B.

To find : 15% of A is equal to what % of B?

Solution :

10% of A is equal to 12% on B.

$\frac{10}{100}\times A=\frac{12}{100}\times B$

i.e. $0.1A=0.12B$

$A=\frac{0.12}{0.1}B$

$A=1.2B$

Now, Let required percentage be 'x'.

So, 15% of A is equal to x% of B

$\frac{15}{100}\times A=x\%\times B$

$\frac{15}{100}\times 1.2 B=x\%\times B$

$x\%=\frac{15}{100}\times 1.2$

$x\%=18$

Therefore, 15% of A is equal to 18% of B.
