Correct Answer: ×, −, ÷, +


Solution : Given:
33 * 4 * 15 * 3 * 61 = 188

Replace * with the mathematical signs and solve the equations one by one using the BODMAS.
First option: +, ×, ÷, –
33 + 4 × 15 ÷ 3 – 61 = 188
Solving the L.H.S. of the equation –
= 33 + 4 × 5 – 61
= 33 + 20 – 61
⇒ –8 ≠ 188
Second option: ×, –, ÷, +
33 × 4 – 15 ÷ 3 + 61
Solving the L.H.S. of the equation –
= 33 × 4 – 5 + 61
= 132 – 5 + 61
⇒ 188 = R.H.S.
Third option: +, –, ÷, ×
33 + 4 – 15 ÷ 3 × 61
Solving the L.H.S. of the equation –
= 33 + 4 – 5 × 61
= 37 – 305
⇒ –268 ≠ 188
Fourth option: ÷, ×, –, +
33 ÷ 4 × 15 – 3 + 61
Solving the L.H.S. of the equation –
= 8.25 × 15 – 3 + 61
= 123.75 – 3 + 61
⇒ 181.75 ≠ 188

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