Question

solve please! very urgent

Answer 1

8 bottles for 5 children were served
for 1 child , bottles required = 8/5= 1.6 bottle
for 40 children , bottles required= 1.6*40 = 64bottles..

THUS 64 BOTTLES ARE REQUIRED FOR 40 CHILDREN

Answer 2

first we will take out how many batches of students are there so therefore 40/5 which is equal to 8 now if 8 bottles are for 5 children or 1 batch so therefore 8×8 is equal to the number of bottles= 64
