A salt manufacturing company produced a total of 100 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? | [
"725",
"800",
"750",
"650"
] | D | Total production of salt by the company in that year = 100 + 200 + 300 + .... + 1200 = 7800.
Average monthly production of salt for that year = 7800/12 = 650.

Two trains of equal are running on parallel lines in the same direction at 44 km/hr and 36 km/hr. The faster train passes the slower train in 36 sec. The length of each train is? | [
"82 m",
"40 m",
"72 m",
"84 m"
] | B | Let the length of each train be x m.
Then, distance covered = 2x m.
Relative speed = 44 - 36 = 8 km/hr.
= 8 * 5/18 = 20/9 m/sec.
2x/36 = 20/9 => x = 40.

THe question seems incorrect. it should not be 80% at the speed of 80. However if it's 20% at the speed of 80, Answer comes out 55.
The question is correct. Here's the explanation:
Let distance be D. We can find the total timeequate it, which comes as:
0.8D / 80 + 0.2D / v = D / 65 => v = 55 (Option D). | AquaRat_train |

A man sold 20 articles for $60 and gained 20%. How many articles should he sell for $60 to incur a loss 20%? | [
"48",
"36",
"40",

] | D | Production cost per article: $60*(100%-20%) / 20 = $2.40
Required production costs for a loss of 20%: $60*(100% + 20%) = $72
Number of articles to be sold for $72 to incur a 20% loss: $72 / $2.40 = 30
