• C. $(40\times 8)-12=36$
• D. $(36+10)÷16=30$

Answer 1

The correct option is D $(36+10)÷16=30$

Option (1) (60÷16)×14=70(60÷16)×14=70
(60÷12)+14=70(60÷12)+14=70
5+14=705+14=70 (this is wrong)
option (2) (55−12)+3=42(55−12)+3=42
(55−16)×3=42(55−16)×3=42
39×3=4239×3=42 (this is wrong)
option(3) (40×8)−12=36(40×8)−12=36
(40+8)−16=36(40+8)−16=36
48−16=3648−16=36 (this is wrong)
option(4) (36+10)÷16=30(36+10)÷16=30
(36×10)÷12=30(36×10)÷12=30
360÷12=30360÷12=30
30=3030=30 (correct)
