The Mean Of Five Numbers Is 28. If One Of The Numbers Is Excluded, The Mean Gets Reduced By 2. Find The Excluded Number? |
|
Answer» Mean of 5 numbers = 28. Sum of these 5 numbers = (28 x 5) = 140. Mean of the REMAINING 4 numbers = (28 - 2) =26. Sum of these remaining 4 numbers = (26 × 4) = 104. EXCLUDED number = (sum of the given 5 numbers) - (sum of the remaining 4 numbers) = (140 - 104) = 36. Hence, the excluded number is 36. Mean of 5 numbers = 28. Sum of these 5 numbers = (28 x 5) = 140. Mean of the remaining 4 numbers = (28 - 2) =26. Sum of these remaining 4 numbers = (26 × 4) = 104. Excluded number = (sum of the given 5 numbers) - (sum of the remaining 4 numbers) = (140 - 104) = 36. Hence, the excluded number is 36. |
