Question

Please help me with this.

Answer 1

56

Explanation:

80% of sixty is 48 so the 20% is 12.

Example:

12 is 40 percent of the next problem.

1. 12/.4 = 30
2. 30*.6 = 18

18 is now 30% of the next strip.

1. 18/.3 = 60
2. 60*.7 = 42

42 now is 75% of the last strip

1. 42/.75 = 56

56 is the Answer.

Answer 2

60x0.8=48
60-48=12
12/0.4=30
30-12=18
18/0.3=60
60-18=42
42/0.75=56
