(5) 31.68
Read Solution (Total 4)
-
- (3) 29.68
Average of the remaining 48 numbers= (50*30 -35 -40)/48= 1425/48=29.68 - 7 years agoHelpfull: Yes(4) No(0)
- Total sum of 48 numbers,
= (50 × 30) – (35 +40)
= 1500 – 75
= 1425
Average = 1425/48 = 29.68 - 5 years agoHelpfull: Yes(2) No(0)
- 29.68
50*30=1500
1500-75=1425
1425/48=29.68 - 7 years agoHelpfull: Yes(1) No(0)
