(84 ÷ 14 ÷ 2 ÷ 9) * ? = 33⅓

(84 ÷ 14 ÷ 2 ÷ 9) * ? = 33⅓

A. 100
B. 300
C. 90,000
D. 10,000
Explanation:
(84 ÷ 14 ÷ 2 ÷ 9) * ? = 33⅓
=> (6 ÷ 2 ÷ 9) * ? = 100 / 3
=> 3 / 9 * ? = 100 / 3
=> ? = 100

Read More (84 ÷ 14 ÷ 2 ÷ 9) * ? = 33⅓

Jameel bought paper sheets for Rs. 7200 and spent Rs. 200 on transport. Paying Rs 600 he had 330 boxes made. Which he said at Rs. 28 each. What is his profit Percentage?

Jameel bought paper sheets for Rs. 7200 and spent Rs. 200 on transport. Paying Rs 600 he had 330 boxes made. Which he said at Rs. 28 each. What is his profit Percentage?

A. 15.5
B. 40
C. 60
D. None of these
Explanation:
330 boxes = Rs. (7200 + 200 600) = Rs. 8000
330 boxes = Rs. (330 × 28) = Rs. 9240
Gain% = (1240/8000 × 100)% = 15.5%

A salt manufacturing company produced a total of 5000 tonnes of salt in January of a particular year. Starting from February its production increased by 100 tonnes every month over the previous months until the end of the year. Find its average monthly production for that year?

A salt manufacturing company produced a total of 5000 tonnes of salt in January of a particular year. Starting from February its production increased by 100 tonnes every month over the previous months until the end of the year. Find its average monthly production for that year?

A. 6060
B. 7070
C. 5550
D. 4440
Explanation:
Total production of salt by the company in that year = 5000 + 5100 + 5200 + …. + 6100 = 66600.
Average monthly production of salt for that year = 66600/12 = 5550
