Total no. of students =25
No. of good student = 72% 25
=(72×100)×25
= 72÷4
= 18
No. of students not good in hindi = 25 - 18
= 7
Hence , 7 students are not good in hindi

Answer: 7
well to find the answer let's understand it
all we need to find is 72% percent of 25, we can do that by
72 x 25 divided by 100 , first we multiply 72 by 50 and then divide it by 100
72 x 25 = 1800
now we divide 1800 by 100
1800/100 = 18
now we got the number of students good in hindi, now to find the number of students bad in hindi we subr=tract 18 from 25
25 - 18 = 7
Hope this was helpful to you ^-^
