In the following question, by using which mathematical operators will the expression become correct:

14 ? 2 ? 4 ? 6 ? 4

÷, ×, > and ×

From potion (A) ⇒ 14 × 2 ÷ 4 > 6 × 4

                      ⇒ 14 ÷ 2 > 24

                      ⇒ 7 > 24 (not true)

From option (B) ⇒ 14 ÷ 2 × 4 > 6 × 4

                      ⇒ 28 > 24 (true)

from option (C)  ⇒14 ÷ 2 + 4 = 6 × 4

                      ⇒ 7 + 4 ≠ 24

                      ⇒ 11 ≠ 24 ( not true)

from option (D) ⇒ 14 ÷ 2 + 4 > 6 × 4

                   ⇒ 7 + 4 > 24

                   ⇒ 11 > 24 ( not true)

therefore option b is correct
