What is the ratio of the total number of students in all the given departments together in 2016 to the total number of students in all the given departments together in 2017?
Correct
Total number of students in 2016 = 125 + 90 + 140 = 355
Total number of students in 2017 = 1.2 × 125 + 0.9 × 90 + 1.1 × 140
= 150 + 81 + 154 = 385
Required ratio = 355: 385 = 71: 77
Hence, option b.
Incorrect
Total number of students in 2016 = 125 + 90 + 140 = 355
Total number of students in 2017 = 1.2 × 125 + 0.9 × 90 + 1.1 × 140
= 150 + 81 + 154 = 385
Required ratio = 355: 385 = 71: 77
Hence, option b.

4. Question
A bought a watch for Rs. 850 and sold it to B at a discount of 20%. If A earns a profit of 20%, then find the marked price of the watch.
Correct
Cost price of the watch = Rs. 850
Profit = 20%
Selling price of the watch = 1.2 × 850 = Rs. 1020
Discount = 20%
Let the marked price of the watch be x.
Then, 0.8x = 1020
x = Rs. 1275
Hence, option c.
