Detailed Explanation & Answer

The formula to get Total boys = Boys % x Difference / (Boys % - Girls %)

Boys from School E
in 2019 = 75 x 280 / 50 = 420
in 2020 = 60 x 136 / 20 = 408
in 2021 = 70 x 264 / 40 = 462
in 2022 = 66 x 224 / 32 = 462

Their total = 420 + 408 + 462 + 462 = 1752
Average = 1752 / 4 = 438

कुल लड़के प्राप्त करने का सूत्र = लड़के % x अंतर / (लड़के % - लड़कियाँ %)

स्कूल ई के लड़के
2019 में = 75 x 280/50 = 420
2020 में = 60 x 136/20 = 408
2021 में = 70 x 264/40 = 462
2022 में = 66 x 224/32 = 462

उनका कुल = 420 + 408 + 462 + 462 = 1752
औसत = 1752/4 = 438

The Correct Answer is 3
