Show answer & explanation
Correct answer: B. 59
Explanation
Empirical relation: Mode = 3 Median − 2 Mean. So 29 = 3 Median − 148, giving 3 Median = 177 and Median = 59.अनुभवजन्य सम्बन्ध: बहुलक = 3 × माध्यिका − 2 × माध्य। अतः 29 = 3 × माध्यिका − 148, जिससे 3 × माध्यिका = 177 और माध्यिका = 59।More Mathematics & Numerical Ability questions
