1.	The average of 4-digit numbers 1x44, x345, 3356 and 41x3 is 2767. What is the average of 6x, 5x +3 and 7x + 3?1. 152. 143. 174. 12
Answer» Correct Answer - Option 2 : 14 Given : The average of 4-digit numbers 1x44, x345, 3356 and 41x3 is 2767 Formula used : Average = Total sum of all observations/ Number of observations Calculations : Average = Total value of all observations/4 2767 = Total value of all observations/4 Total value of all observations = 2767 × 4 = 11068 1x44 + x345 + 3356 + 41x3 = 11068 Now we should put value of x less than 3 as at x = 3 sum of these numbers will be more than 11068 At x = 2, values get satisfied Now average of 6x, 5x + 3 and 7x + 3 Average = (6x + 5x + 3 + 7x + 3)/3 Average = (6 × 2 + 5 × 2 + 3 + 7 × 2 + 3)/3 ⇒ 42/3 = 14 ∴ The average will be 14

The average of 4-digit numbers 1x44, x345, 3356 and 41x3 is 2767. What is the average of 6x, 5x +3 and 7x + 3?1. 152. 143. 174. 12

Answer» Correct Answer - Option 2 : 14

Given :

The average of 4-digit numbers 1x44, x345, 3356 and 41x3 is 2767

Formula used :

Average = Total sum of all observations/ Number of observations

Calculations :

Average = Total value of all observations/4

2767 = Total value of all observations/4

Total value of all observations = 2767 × 4 = 11068

1x44 + x345 + 3356 + 41x3 = 11068

Now we should put value of x less than 3 as at x = 3 sum of these numbers will be more than 11068

At x = 2, values get satisfied

Now average of 6x, 5x + 3 and 7x + 3

Average = (6x + 5x + 3 + 7x + 3)/3

Average = (6 × 2 + 5 × 2 + 3 + 7 × 2 + 3)/3

⇒ 42/3 = 14

∴ The average will be 14
