(b) 2000

(c) 2900

(d) 350

Step-by-step explanation:

(a) 777 + 167 + 223

 = 777 + 223 + 167

 = 1000 + 167

 = 1167

(b) 872 + 134 + 128 + 866

  = 872 + 128 + 134 + 866

  = 1000 + 1000

  = 2000

(c) 2478 + 454 + 22 - 54

 = 2478 + 22 + 454 - 54

 = 2500 + 400

 = 2900

(d) 47 +48 +49 +50 +51 +52 +53

 = 47 + 53 + 48 + 52 + 49 + 51 + 50

 = 100 + 100 + 100 + 50

 = 350
