The efficiency of the ramp can be calculated using the formula:

Efficiency = (Output Work / Input Work) x 100%

Here, the input work is 1200 joules and the output work is 300 joules.

Efficiency = (300 / 1200) x 100%
Efficiency = 0.25 x 100%
Efficiency = 25%

Therefore, the efficiency of the ramp is 25%. This means that only 25% of the work put into pushing the box up the ramp is actually output as useful work in moving the box. The remaining 75% of the work is lost due to friction, air resistance, and other factors.
