1. A debugging program rectify 0.128 errors in every second. Approximately how many seconds will it need to rectify 25 errors?

A. 109

B. 261

C. 195

D. 201

**Answer : ****195**

Time taken to rectify 0.128 errors is 1 second.

Time taken to rectify 25 errors --> X

Here the number of errors has been increased, so time also increases. Hence error is directly proportional to time.

X = (25 / 0.128) * 1

X = 25 * 1000 / 128

X = 195.31

Therefore, time taken to rectify 25 errors is 195 sec approximately.

2. Running at the same constant rate, 6 identical machines can produce a total of 270 bottles per minute. At this rate, how many bottles could 10 such machines produce in 4 minutes?

A. 648

B. 1800

C. 2700

D. 3600

**Answer : ****1800**

Let the required number of bottles be Rs. y.

More machines, More bottles (Direct Proportion)

More minutes, More bottles (Direct Proportion)

6 x 1 x y = 10 x 4 x 270

y= 1800
