Answer 1

Answer:

9. Amount of sulphur = 10%

10. Total Salary = 36,000

11. Company A = 67,200 Company B = 25,200 Company C = 1,17,600

12. 30,800 votes

Step-by-step explanation:

10. Let total salary = x

total Money spend = 66%

total money left = 12,240 (34%)

According To Question

34% of X = 12,240

34/100 × X = 12,240

X = 12,240 × 100/34

X = 36000

11. Invested in company A = 32%

Invested in company B = 12%

Invested in company C = 100% - (32% + 12%)

= 56%

Total Money invested = 2,10,000

In company A = 32% × 2,10,000

= 67,200

In company B = 12% × 2,10,000

= 25,200

In company C = 56% × 2,10,000

= 1,17,600

12. 55,000 × 56%

55,000 × 56/100

= 30,800
