Forget conventional ways of solving math questions. In PS, IVY approach is the easiest and quickest way to find the answer.

A. 7,000
B. 24,000
C. 40,000
D. 100,000
E. 168,000
Since 7 days consist of 24*7 hours the total hours of a week is 168 hours.
Since every hour the machine produces 1000 units of product P the total product during 168 hours is 168,000.
The answer is, therefore, (E).

The efficiency of the machine is 1000 units/p hour
7 days = 24*7 => 168 Hours..
So, No of units produced is 168000 units, answer must be (E)

Since there are 24 hours in a day, the machine can produce 1000 x 24 x 7 = 168,000 units of product P in 7 days.
Answer: E

A certain machine produces 1,000 units in 1 hour
So, the machine produces 24,000 units in 24 hours
In other words, the machine produces 24,000 units in 1 DAY
So, the machine produces (24,000)(7) units in 7 DAYS
(20,000)(7) = 140,000
So, (24,000)(7) = some number greater than 140,000
Answer: E
Cheers,
