Answer: 1/24
Explanation 1. 3/4 of the students do not know either Hindi or English. This means that 1 - 3/4 = 1/4 of the students know either Hindi or English or both. 2. 1/6 of the students know English. 3. 1/8 of the students know Hindi. Now, let's use the principle of inclusion-exclusion: Number of students who know either Hindi or English or both = Number of students who know English + Number of students who know Hindi - Number of students who know both We know that 1/4 of the students know either Hindi or English or both. We also know the number of students who know English (1/6) and the number of students who know Hindi (1/8). Let x be the number of students who know both English and Hindi. Then, we can set up the equation: 1/4 = 1/6 + 1/8 - x Combine like terms: 1/4 = 7/24 - x Add x to both sides: x = 7/24 - 1/4 x = 7/24 - 6/24 x = 1/24 So, 1/24 of the students know both English and Hindi.
