Answer»

AVERAGE marks of 5 batches of 20, 25, 30, 15 & 35 students are 40, 35, 30, 40 & 35.

Therefore, the average Score for all the students is:

$(= \frac{{\left[ {\left( {20 \times 40} \RIGHT) + \left( {25 \times 35} \right) + \left( {30 \times 30} \right) + \left( {15 \times 40} \right) + \left( {35 \times 35} \right)} \right]}}{{\left( {20 + 25 + 30 + 15 + 35} \right)}} = \frac{{4400}}{{125}})$

= 35.20

Hence, the average score of all the students put TOGETHER is 35.20.
