Correct Answer: – and ×

Solution : Given:
11 – 2 × 16 + 19 = 25

Replace the given symbols in the options one by one with the original symbols in the given equation.
First option: – and +
11 – 2 × 16 + 19 = 25
⇒ 11 + 2 × 16 – 19
⇒ 11 + 32 – 19 = 24
⇒ 24 ≠ 25
Second option: = and +
11 – 2 × 16 + 19 = 25
⇒ 11 – 2 × 16 = 19 + 25
⇒ 11 – 32 = 44
⇒ –21 ≠ 44
Third option: – and ×
11 – 2 × 16 + 19 = 25
⇒ 11 × 2 – 16 + 19 = 25
⇒ 22 – 16 + 19 = 25
⇒ 25 = 25
Fourth option: × and +
11 – 2 × 16 + 19 = 25
⇒ 11 – 2 + 16 × 19 = 25
⇒ 11 – 2 + 304 = 25
⇒ 313 ≠ 25

So, only the third option satisfies the equation. Hence, the third option is correct.
