Answer 1

Answer:

Ans A is 200 and B is 3×200=600

Step-by-step explanation:

Let's take A is X and B is 3X

So as stated in question, if A increased by 30% then A will be X×130/100=13X/10

And if B is decreased by 20% then the value of B will be 3X×80/100=24X/10

Said, 13X/10+24X/10=740

»37X=7400 »X=7400÷37=200

So, A is 200 and B is 3×200=600

Hope I have clarified all step by step and it may help you.

That's all.
