A soap company produces two kinds of soaps having weight 500 gm and 650 gm, respectively. If 200 soaps of the first kind and 300 soaps of second the kind were produced, then what is the weighted average weight (in gm) of the soaps?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 590.
Total weight = (200 × 500) + (300 × 650) = 100,000 + 195,000 = 295,000 gm
Total soaps = 200 + 300 = 500
Weighted average = 295,000 ÷ 500 = 590 gm
