Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 550.
Given that
The total runs scored during 2019–2020 = 4000
The total runs scored against New Zealand and Pakistan during 2019–2020 = (14% + 16%) × 4000 = 30 × 4000/100 = 1200
Now,
The total runs scored during 2020–2021 = 5000
The total runs scored against sri Lanka and Pakistan during 2020–2021 = (20% + 15%) × 5000 = 35 × 5000/100 = 1750
Hence, the required difference = 1750 - 1200 = 550
