Keira Conrad · Answer 1

The correct answer is option A: B=9s

Step-by-step explanation:

Let the time taken to do the homework by David be = D

Let the time taken to do the homework by Ben be = B

Let the time taken to do the homework by Sandro be = S

As Ben spent triple the amount of time on the homework as David so

B = 3D ... (1)

Also given is, David spent 3 times more than Sandro. So, D = 3S ... (2)

Putting the value of D in equation (1)

B = 3 (3S)

Hence, B = 9S
