Average Bitcoin Transaction = (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120) / 8 = 3480

the transaction years, below the average = 2010-11, 2012-13, 2013-14, 2014-15, 2017-18

The years above the average = 2011-12, 2015-16, 2016-17

 

Hence, the ratio will be 3:5.

Transactions in 2016-17 = 5040

Transactions in 2013-14 = 3360

Answer will be 5040/3360 = 1.5

First the years in which transaction rose compared to previous year = 2011-12, 2013-14, 2015-16, 2016-17

Percentage increase in these years compared to last year, 2011-12 = (3720 – 2640)/ 2640 × 100 = 40.9090%

2013-14 = (3360 – 2520)/ 2520 × 100 = 33.33%

2015-16= (4320 – 3120)/ 3120 × 100 = 37.88%

2016-17 = (5040 – 4320) / 4320 × 100 = 16.67%

Hence, the ans. Is 2011-12.

Average bitcoin transaction is 3480. bitcoin transactions in 2015-16 = 4320.

Hence, percentage = [4320/ 3480] × 100 = 124.14% = 125%

We need to calculate percentage of students who cleared TCS NQT in 2018,

As shown above, there are 20 students who cleared TCS NQT in 2018.

And, Total students are 170

Hence, 20/170 × 100 = 11.76%

Total students = 170

No. of students who are in none category = 30

Therefore, percentage of students who have cleared at least one = [(170 – 30) / 170] × 100 = 82.35%
