Observing the bar graph,(a) \\\\(4\\\\) students have failed and obtained less than \\\\(40\\\\) marks \\\\((30-39)\\\\)(b) \\\\(7\\\\) and \\\\(11\\\\) students have obtained the marks \\\\((50-59)\\\\) and \\\\((60-69)\\\\) respectively.Therefore, \\\\(7 + 11=18\\\\)\\\\(18\\\\) students have obtained \\\\(60\\\\) to \\\\(69\\\\) marks.(c) \\\\(4\\\\) students secured \\\\(90\\\\) and above marks.(d) \\\\(6\\\\) students got \\\\(80\\\\) to \\\\(89\\\\) marks and \\\\(4\\\\) students got \\\\(90\\\\) to \\\\(92\\\\).Hence, \\\\(6+4=10\\\\) students are merit holders.(e) Total number of students in the class \\\\(=4+2+7+11+8+6+4=42\\\\)
