Step-by-step explanation:

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

100

10

×A=

100

12

×B

i.e. 0.1A=0.12B0.1A=0.12B

A=\frac{0.12}{0.1}BA=

0.1

0.12

B

A=1.2BA=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

100

15

×A=x%×B

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

100

15

×1.2B=x%×B

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

100

15

×1.2

x\%=18x%=18

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