Solve this problem without using Arithmetic progression(1901+1902+1903+.........+1993)-(101+102+103+..........+193)

Answer»

(1901 + 1902 + 1903+.....+1993) - (101 + 102 + 103+....+193)

= (1800+101 +1800+102 +1800+103 +....+ 1800+193) - (101 + 102 + 103+....+193)

= (1800 + 1800 + 1800+.....) 93 TIMES
= 1800 × 93 = 167400
