Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. The average achievement of the girls is more than that of the boys.
According to the given table,
Total achievement of boys = 56 + 75 + 34 + 49 + 89 + 99 + 94 + 59 + 82 + 79
⇒ 716
Average achievement of boys = 716/10 = 71.6
Total achievement of girls = 35 + 88 + 85+ 99 + 67 + 82 + 97 + 63 + 79 + 81
⇒ 776
Average achievement of girls = 776/10 = 77.6
Hence the average achievement of the girls is more than that of the boys.
