Correct Answer: ÷, ×, +, =, +

Solution : Given:
24 _ 6 _ 3 _ 4 _ 10 _ 6

Replace _ with the mathematical signs and solve the equations one by one using BODMAS.
First option: ÷, ×, =, +, +
24 ÷ 6 × 3 = 4 + 10 + 6
L.H.S. = 24 ÷ 6 × 3 = 4 × 3 = 12
R.H.S. = 4 + 10 + 6 = 20
L.H.S. ≠ R.H.S.
Second option: ÷, ×, +, =, +
24 ÷ 6 × 3 + 4 = 10 + 6
L.H.S. = 24 ÷ 6 × 3 + 4 = 4 × 3 + 4 = 12 + 4 = 16
R.H.S. = 10 + 6 = 16
L.H.S. = R.H.S.
Third option: ÷, ×, –, =, ×
24 ÷ 6 × 3 – 4 = 10 × 6
L.H.S. = 24 ÷ 6 × 3 – 4 = 4 × 3 – 4 = 12 – 4 = 8
R.H.S. = 10 × 6 = 60
L.H.S. ≠ R.H.S.
Fourth option: +, =, ÷, ×, +
24 + 6 = 3 ÷ 4 × 10 + 6
L.H.S. = 24 + 6 = 30
R.H.S. = 0.75 × 10 + 6 = 7.5 + 6 = 13.5
L.H.S. ≠ R.H.S.

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