Answer:
multiple choice?
Step-by-step explanation:
Answer:
Arav is 30 and Pawan is 40
Step-by-step explanation:
We can call Arav's age x and Pawan's age x + 10, therefore we can write the following equation:
1/7((x + 10) - 5) = 1/5(x - 5)
1/7(x + 5) = 1/5(x - 5)
5(x + 5) = 7(x - 5)
5x + 25 = 7x - 35
-2x = -60
x = 30 so x + 10 = 40
-15 / 20 = -0.75
-2/3 = -0.66
-9/12 = -0.75
-12/16 = -0.75
-25/30 = -0.83
Therefore B and C are the correct answers.
