Solution

On applying the BODMAS rule, we get:

2550 $-$ [510 $-$ {270 $-$ (90 $-$ $80 + 70$ )}]
= 2550 $-$ [510 $-$ {270 $-$ (90 $-$ 150)}] (On simplifying vinculum)
= 2550 $-$ [510 $-$ { 270 $-$ ( $-$ 60)}] (On simplifying parentheses)
= 2550 $-$ [510 $-$ 330] (On simplifying braces)
= 2550 $-$ 180
= 2370
