Question

80% of the total number of a student of a school did not go for picnic on a certain day if the number of student who went for a picnic was 240 find the total number of student in the school​

Answer 1

Answer:

total number of students in school =1200

Step-by-step explanation:

Total number of students who went for picnic = 240

this is equal to 20% of the total students in the school (100-80)

Therefore total students in the school = 240*100/20=1200

Answer 2

Let the total number of students be =x
No. Of students went to picnic were=240
According to questions 80% students didn't go so the remaining students were (100-80)%= 20%
So equation formed will be
20% of x= 240
20/100 *x = 240
x= 240*100/20
x= 1200
Total number of students are 1200
