What is the value of 1980 ÷ 9 + [ - 77 + {-1980 + (1/4 of 7920)}]?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 143.
1980 ÷ 9 + [-77 + {-1980 + (1/4 × 7920)}]
= 1980 ÷ 9 + [-77 + {-1980 + (7920/4)}]
= 1980 ÷ 9+ [-77 + {-1980 + (1980)}]
= 1980 ÷ 9+ [-77 + {-1980 + 1980}]
= 1980 ÷ 9 + [-77]
= 220 + [-77]
= 220 - 77
= 143
