Question

Слесарь за 4ч по норме должен изготовить 84 детали. За первые 3ч он изготовил 72 детали. На сколько деталей его производительность выше нормы ?

Answer 1

1. 72:3=24 (д.) - за 1 ч, если выше нормы
2. 24*4=96 (д.) - за 4 ч, если выше нормы
3. 96-84=12 (д.) - выше нормы

Answer 2

Calculation of Productivity

To calculate how many parts the locksmith's productivity exceeds the norm, we need to find the difference between the number of parts he actually produced and the norm.

The locksmith is expected to produce 84 parts according to the norm. However, he only produced 72 parts in the first 3 hours.

To find the difference, we subtract the number of parts produced from the norm:

84 - 72 = 12

Therefore, the locksmith's productivity exceeds the norm by 12 parts.
