Answer» We know, AVERAGE of quantities = SUM of all quantities/no. of quantities The average age of 7 boys is 14 YEARS. Then total age of 7 boys = 7 × 14 = 98 years. A boy AGED 14 years died, So now the total age of remaining 6 boys = 98 – 14 = 84 years. ∴ The average age of remaining 6 boys = 84/6 = 14 years. |
