Question

if average of 7 consecutive number is 203, then the average of the smallest & second number is a) 203 b) 201 c) 202.5 d) 203.5

Answer 1

Step-by-step explanation:

let numbers be x,x+1,x+2,x+3,x+4,x+5,x+6

x,x+1,x+2,x+3,x+4,x+5,x+6/7=203

7x+21=1421

7x=1400

x=200

smallest number=x=200

second number =x+1=201

The average of first number and second number = 200+201/2=401/2=200.5
