Answer 1

Common Calculation

For shop A,

Number of copper items sold in shop A is 24.

Number of bronze items sold in shop A is 16.

So, total number of copper and bronze items sold in shop A is 24 + 16 = 40.

So, Ratio between total number of [ copper + bronze] items sold to number silver items sold.

So, Number of silver items sold in shop A is 40 × 4 /5 = 32

Similarly, we can calculate others values also, which is given in the table.

Calculation

In Shop D:

Copper = 36

→ Shop E = 36 × 1.25 = 45

Bronze = 24

→ Shop E = 24 × 1.125 = 27

Silver = 40

→ Shop E = 40 × 1.30 = 52

Total in Shop E = 45 + 27 + 52 = 124

Total in Shop C = 32 + 18 + 36 = 86

Difference = 124 – 86 = 38

Answer: 38
