Simplify: \(60-[18-\{9-(12-3\times2)\}]\)
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 45
Brackets are removed from the innermost outwards: first ( ), then { }, then [ ]. Inside each bracket, BODMAS still applies, so multiplication comes before subtraction.
( ): \(12-3\times2=12-6=6\)
{ }: \(9-6=3\)
[ ]: \(18-3=15\)
\(60-15=45\)
