Answer:

(3) 122 is the answer

Step-by-step explanation:

81+[159-2{7×8+(13-2×5)}]

By using BODMAS rule

B = Bracket

O = Of

D = Divide

M = Multiply

A = Addition

S = Subtraction

→ 81+[159-2{7×8+(13-2×5)}]

→ 81+[159-2{7×8+(13-10)}]

→ 81+[159-2{7×8+(3)}]

→ 81+[159-2{7×8+3}]

→ 81+[159-2{56+3}]

→ 81+[159-2{59}]

→ 81+[159-118]

→ 81+[41]

→ 81+41

→ 122 is the answer
