                        View Hint View Answer Discuss in Forum Let, 8888 +7777 + 666 + x = 19000 
 Now solve for x.Correct Option: CLet, 8888 +7777 + 666 + x = 19000 
 Then, 17331 + x = 19000
 ∴ x = 19000 - 17331 = 1669

                        View Hint View Answer Discuss in Forum Let 4003 - x - 1599 = 716 
 Then, x = 4003 - 1599 - 716
 Correct Option: BLet, 4003 - x - 1599 = 716 
 Then, x = 4003 - 1599 - 716
 = 4003 - (1599 + 716)
 = 4003 - 2315
 = 1688
